Answer: x = -9
Step-by-step explanation:
3x + 2x = 5x
7x + 5 - 5 = 5x - 13 - 5
Subtract 5 from both sides
7x + 5 - 5 = 5x - 13 - 5
simplify
7x = 5x - 18
Subtract 5x from both sides
7x - 5x = 5x -18 - 5x
simplify
2x = -18
divide both sides by 2
[tex]\frac{2x}{2}[/tex] = [tex]\frac{-18}{2}[/tex]
simplify
x = -9
