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
First expand the parentheses using the distributive law:-
-8 = 28x - 56 + 8x - 24
36x - 80 = -8
36x = 72
x = 2 is the answer
