8m + 9 = 7m + 8
Subtract 7m on both sides.
8m - 7m + 9 = 7m - 7m + 8
8m - 7m + 9 = 8
m + 9 = 8
Subtract 9 on both sides.
m + 9 - 9 = 8 - 9
m = 8 - 9
m = -1
Your solution is m = -1.
Subtract 7m on both sides.
8m - 7m + 9 = 7m - 7m + 8
8m - 7m + 9 = 8
m + 9 = 8
Subtract 9 on both sides.
m + 9 - 9 = 8 - 9
m = 8 - 9
m = -1
Your solution is m = -1.
