Answer:

x = -8

Step-by-step explanation:

-8x + 3(x - 5) = 25

Distribute the 3 into the (x - 5).

-8x + 3x - 15 = 25

Combine like terms.

-5x - 15 = 25

Add 15 to both sides.

-5x = 40

Divide both sides by -5.

x = -8.

Proof:

-8x + 3(x - 5) = 25

Substitute variable.

-8(-8) + 3((-8) - 5) = 25

Subtract inside parenthesis.

-8(-8) + 3(-13) = 25

Multiply -8 and -8.

64 + 3(-13) = 25

Multiply 3 and -13.

64 + (-39) = 25

Add 64 and -39.

25 = 25
