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
