We are given equation 12 am =4.
We need to solve it for a variable.
In order to solve it for a variable, we need to get rid 12 and m from left side.
Let us eliminate 12 from left side by dividing.
Dividing both sides by 12, we get
12am /12 = 4/12
am = 1/3.
Now, we need to get rid m from left side.
Dividing m on both sides, we get
am/m = 1/3m
a = 1/3m
