Mom's product must be a high-quality product.

There is no doubt about it.

What good things are waiting for Lin Xiaofan to open this time?

I want to see my mother - no, I want to hear my mother's voice, and the gifts my mother gives me are also what I want, so you can have both together, why not laugh and accept it?

The torch in Lin Xiaofan's heart has burned hotly, the flame directly penetrates through the eyes, shooting out a hot wolf light, and the little hand has long been eager to output spiritual power, pressing on the "Made in China" of the brick.

There was no accident, Lin Xiaofan was successfully brought into the brick space again, and the first thing he saw was still a golden strange question - okay! The so-called strange question is just an incomprehensible book of heaven compared to the natives of the Tianyun Continent, but for Lin Xiaofan, this is just an ordinary earth algebra topic.

Different from the previous direct solution, this time it is a simple system of binary linear equations: 5x+3y=24, 7x+6y=39, find x,y.

This......

Mom, since we have long been determined that we are your son, is it necessary to play with these earth things? If you can't just give it directly, why spend all this time?

Mom, I guess she's a very naughty master.

Lin Xiaofan thought speechlessly.

But there's no way, if you want to get what your mother left behind, you have to play according to the rules of the game left by your mother, otherwise...... Who knows what weird means Mom will leave to punish herself?

Be honest.

Be a son more honestly.

Yes, it is the right thing to solve the problem honestly.

Could it be 3 again?

It's just that this is a binary equation, there are two unknowns, even if one is 3, it can't be both 3, right?

Lin Xiaofan had the intention to try 3 generations, but he thought that this was an almost obvious topic, so why bother to replace it? If not, wouldn't it be a waste of time?

The questions are very simple, really simple, and they completely belong to the category of sending points.

Because of 3y and 6y, as long as you multiply 5x+3y=24 by 2, and subtract 7x+6y=39, you get 3x=9, and x is equal to -! X is really 3, and my mother really loves to play.

Lin Xiaofan was speechless, but quickly continued his answer:

Substituting 3 into 5x+3y=24, we get 3y=9, y is equal to - by god, y is also 3.

Mom! Is it interesting to set such an answer to such a question?

When Lin Xiaofan was speechless, this golden equation immediately disappeared without a trace after he had obtained his correct answer, and at the same time, his voice reappeared: "Congratulations!" The answer is correct, and the fifth floor of the slab brick space is officially opened. ”

The space of the bricks has become larger, reaching a space of 50 square meters.

Although it is still not as big as those storage rings obtained, it has reached half of their space, and this is a "growth" space, who knows how big the slab space will be as the level increases?

Besides, as a matter of common sense, storage equipment cannot store another storage equipment, otherwise it will cause instability in the storage space, which may cause the storage equipment to malfunction, destroy the items in the storage space, and more seriously, the damage to the storage equipment - irreparable damage.

This is the general theory of storage equipment in the Tianyun Continent.

However, the slab brick space ignores this general theory, and it is accepted when it comes, and there is a great tendency to embrace all rivers, which shows the extraordinaryness of the slab brick.

Another thing that made Lin Xiaofan happy was that the space of the bricks had increased by one or two times before, but this time it had increased to five times the original amount, which was really exciting.

Hey, hey, hey...... Big! Big! Big! When you have time one day, when you return to Qingtian, you must take all the trees of Eucommia in your own hands, and then you can feel at ease.

The people of the Tianyun Continent don't know the treasure of the Eucommia Tree now, but what if one day a neuropathy accidentally discovers it?

What can I do?

This is the most precious treasure of the Sun, and it is also equivalent to countless amounts of money to a certain extent.

Money, money, money...... Lin Xiaofan is not a money fan, but he is not against having a lot of money, the more the better, even if he counts the money until his hands cramp......

"Stinky boy! Do you miss your mother? ”
