4−2(7+8x)=12−6(2x−7)+4x

4−2(7+8x)=12−6(2x−7)+4x

4+(−2)(7)+(−2)(8x)=12+(−6)(2x)+(−6)(−7)+4x(Distribute)

4+−14+−16x=12+−12x+42+4x

(−16x)+(4+−14)=(−12x+4x)+(12+42)(Combine Like Terms)

−16x+−10=−8x+54

−16x−10=−8x+54

Step 2: Add 8x to both sides.

−16x−10+8x=−8x+54+8x

−8x−10=54

Step 3: Add 10 to both sides.

−8x−10+10=54+10

−8x=64

Step 4: Divide both sides by -8.

−8x−8=64−8

x=−8
