Answer:
m = 4
Step-by-step explanation:
We are given the expression 12m - 15 = 3(2m + 3) and are asked to solve for m.
To solve we need to isolate m, but first, get rid of the parenthesis by distributinh the m by the two numbers inside the parenthesis.
12m - 15 = (3(2m) + 3(3)
12m - 15 = 6m + 9
Now isolate m, add 15 to both sides :
12m = 6m + 24
Subtract 6m from both sides :
6m = 24
Divide 6 by both sides :
m = 4
