Answer:
m = 7
Step-by-step explanation:
2(m + 2) = 18
the first step is to distribute the 2 so we don't have parenthesis
2 x m = 2m and 2 + 2 = 4
now we're left with 2m + 4 = 18
we want to get m alone on one side so we have to subtract 4 from both sides
2m + 4 = 18
-4 -4
we are left with 2m = 14
the last step is to divide and since we want m alone, we have to divide 2 from both sides
2m/2 = m
14/2 = 7
so m = 7
