Question

Solve for x:
-15x + 5 = -10x + 25

Answer 1

the answer is negative 4

Answer 2

-4 (negative 4)

Explanation:

-15x + 5 = -10x + 25

First subtract 5 from both sides

-15x = -10x +20

Then, add 10x to both sides

-5x = 20

Now, Divide both sides by -5

x = -4

To check you work substitute x for -4 in the original problem.

-15(-4) + 5 = 65

-10(-4) +25 = 65
