What is the solution to the equation?

3 (x - 5) = 8x - 30

A.

x = - 5

B.

x = - 3

C.

x = 3

D.

x = 5

C. x=3 because you need to distribute the 3 to the x and the - 5. This will get you 3x-15 = 8x-30. Then, you have to subtract 3x from both sides. - 15=5x-30. Lastly, you add 30 to both sides. 15=5x. Divide both sides by 5 and you have x=3.

3 (x - 5) = 8x - 30

Distribute 3 into the parenthesis:

3x - 15 = 8x - 30

Add 15 to both sides:

3x = 8x - 15

Subtract 8x to both sides:

-5x = - 15

Divide - 5 to both sides:

x = 3
