7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps

7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5

x=6

7x-5x=8 2x=8 x=4

It is: 12x

x = -5

5x+32+7x+8=180. By the laws of commutativity we can thus say that 12x+40=180. Subtracting 40 we get 12x=140. Divide by 12 and you get x=(do it yourself) This has nothing to do with calculus by the way.

5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70

The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
