7/8m - 4 = -15/16m + 1...if u want to get rid of the fractions, multiply entire equation by the lowest common denominator, which is 16
14m - 64 = - 15m + 16
14m + 15m = 16 + 64
29m = 80
m = 80/29
or u can do it with the fractions...
7/8m - 4 = -15/16m + 1
7/8m + 15/16m = 1 + 4
14/16m + 15/16m = 5
29/16m = 5
m = 5 * 16/29
m = 80/29
