A:
To answer this question you should get rid of like terms: 8x+6x-44=66-8x *remember to cross out the terms you use 14x-44=66-8x (I can't show it on the computer) -14x +66 +66-14x _________________ 22=-22x divide by -22 divide by -22 ______________________ -1=x (right answer)
Friend maybe wrong: with calculations and may have gotten 22=-2x (wrong)
