Question

Which of the following equations is equivalent to -5(x-1)=2x+15

Select one:
-7x =14
-7x =20
-7x =10
-7x =16

Answer 1

-7x = 10

Explanation:

step 1: multiply each term inside the parentheses by -5, to get:

-5x + 5 = 2x + 15

you can subtract 2x from each side of the equation to get:

-7x + 5 = 15

now you subtract 5 from each side to get:

-7x = 10
