Question

Simplify 3(x - 6) - 4(x 3).
a. -x - 30
b. -x - 9
c. -x - 6
d. -x2 - 30

Answer 1

-x-30

Explanation:

first you need to distribute:

3(x)+3(-6) -4(x)+ (-4)(3)

Then you multiply:

3x+(-18)-4x+(-7)

then you combine like terms:

3x-4x= -1x

-18+(-7)= -25

simplified:

-1x-30

Answer 2

3(x - 6) - 4(x + 3) = 3x - 18 - 4x - 12 = -x - 30
