You and a friend are doing math homework together. you have to solve the equation 8 x plus 6 x minus 44 equals 66 minus 8 x8x+6x−44=66−8x. your friend arrives at the incorrect answer x = 11. find the correct value of x. then find the error your friend possibly made.

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)
