M = 9M=9

Explanation:

First, isolate the MM terms on one side of the equation and the constants on the other while keeping the equation balanced:

5M + 24 - 24 - 2M = 51 + 2M - 24 - 2M5M+24242M=51+2M242M

5M - 2M + 24 - 24 = 51 - 24 + 2M - 2M5M2M+2424=5124+2M2M

5M - 2M + 0 = 51 - 24 + 05M2M+0=5124+0

5M - 2M = 51 - 245M2M=5124

Now consolidate like terms:

(5 - 2)M = 27(52)M=27

3M = 273M=27

Finally, solve for MM while keeping the equation balanced:
(3M)/3 = 27/33M3=273

(cancel(3)M)/cancel(3) = 27/3

M = 27/3

M = 9
