If you're trying to find the value of x, I've written it step by step here:
-5x = 60 + 7x
First we isolate x. To do this, subtract 7x from both sides.
-12x = 60
Now we divide both sides by -12.
x = -5

7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps
x=12
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
many solutions
7x = 21 x = 3
