Answer
$m=63$
Work Step by Step
We need to get the m alone. Thus, we cancel out the subtraction by adding 3 on both sides. This leaves us with the equation $m/7=9$. In order to cancel out division, we use multiplication, so we multiply both sides by 7 to get that m=63. We plug 63 in for m and confirm that our answer is, indeed, correct.
