-8=-7(-4x+8)+8(x-3) what does x equal? and how do i get the answer?
malfutka [58]

Hello there

the answer your looking for is x=2

Step 1: Simplify both sides of the equation.

−8=−7(−4x+8)+8(x−3)

−8=(−7)(−4x)+(−7)(8)+(8)(x)+(8)(−3)(Distribute)

−8=28x+−56+8x+−24

−8=(28x+8x)+(−56+−24)(Combine Like Terms)

−8=36x+−80

−8=36x−80

Step 2: Flip the equation.

36x−80=−8

Step 3: Add 80 to both sides.

36x−80+80=−8+80

36x=72

Step 4: Divide both sides by 36.

36x

36

=

72

36

x=2

thank you
