4x + 18 = 10x
Subtract 4x from both sides
18 = 6x
Divide by the coefficient to get X by itself.
3 = x
Each of the square's sides = 3.

Since you know the sides are equal you can make an equation setting them equal to each other:

4x+18=10x

Now we solve. We want all the ones with x values on one side so we move the 4x to the right side by subtracting 4x from both sides.

18-4x+4x=10x-4x
18=6x

Now, we can divide both sides by 6 to get the value of x
18/6=6x/6
3=x

I hope that helps.
