You need to get the variable (letter) on one side of the equation by itself.
What you do to one side of the equation you do to the other.
51m = 3
divide both sides by 51 to get
m = 3/51

4y = 9
divide both sides by 4 to get
y = 9/4
simplify the 9/4 to 2 1/4
y = 2 1/4

4y = 9
divide BOTH sides by 4 to get:
y = 9/4

51m = 3
divide BOTH sides by 51 to get:
m= 3/51 =1/17

16b = 2
divide BOTH sides by 16 to get:
b= 2/16 = 1/8
