You and a friend are doing math homework together you have to solve the equation 5X + 4X -68 equals 34 - 8X. Your friend arrives at the incorrect answer X equals -2 find the correct value of X then find the error your friend possibly be made

the correct answer

x = 6

Step-by-step explanation:

5x+4x-68=34-8x, combine like terms

9x-68=34-8x, add 68 to both sides

9x=102-8x, add 8x to both sides

17x=102, divide both sides by 17

x=6

your friend's answer is the same work, but instead of adding 68 to both sides, it was subtracted from 34 giving a -34 instead of 102.

9x=-34-8x

17x= -34

x = -2
