Answer:

<h2>x = -1</h2>

Step-by-step explanation:

2x+10+3x=7x+12\qquad\text{combine like terms}\\\\(2x+3x)+10=7x+12\\\\5x+10=7x+12\qquad\text{subtract 10 from both sides}\\\\5x+10-10=7x+12-10\\\\5x=7x+2\qquad\text{subtract}\ 7x\ \text{from both sides}\\\\5x-7x=7x-7x+2\\\\-2x=2\qquad\text{divide both sides by (-2)}\\\\\dfrac{-2x}{-2}=\dfrac{2}{-2}\\\\x=-1

First, get all common variables (x and integers in this case) onto the same side.
2x + 3x - 7x = 12 - 10
-2x = 2
x = -2/2
x = -1
