-5/6 = x - 1/4
(1)If you do not want to work with fractions, get rid of them
-5/6 = x -1/4
6( -5/6 = x -1/4)
-30/6 = 6x - 6/4
-5 = 6x -6/4
4( -5 = 6x -6/4)
-20 = 24x -24/4
-20 = 24x - 6
-20 + 6 = 24x - 6 + 6
-14 = 24x + 0
-14/24 = 24x/24
-7/12 = x

-1/21=m+ 2/3
21(-1/21 = m + 2/3)
-21/21 = 21m + 42/3
-1 = 21m + 14
-1 - 14 = 21m + 14 - 14
-15 = 21m + 0
-15/21 = 21m/21
-5/7 = m
