Question 754635
Here is a solution to this problem.  Where is the mistake? Correct it and give the right answer.

3(y + 4) -42 = 2y + 3(y+4) +10
3y +12-42 = 2y +3y +12 +10
3y -30 = 5y + 22
3y -30 +30 = 5y +22 -30  ****** 30 added to one side, -30 to the other.
=======================
3y =5y -8
3y -5y =5y - 5y -8
-2y/-2 = -8/-2
y=-4
