x+x+2x+3-2=37
First you move all thevariables(x's) the left and the constant to the right.
x+x+2x+3-2=37
You then move the positive 3 to the right which turns into a negative 3. And the negative 2 to the right which turns into positive 2. You move the constant to the right and the charges change to the opposite of what the charge was.
x+x+2x=-3+2+37
You add them up together.
x+x+2x
It turns into 4x
-3+2+37
Equals to 36
4x=36
You then divide 36 by 4 and it equals to 9. Because 9 times 4 equals to 36.
x=9
Hope this help you.
