Work Step by Step
We need to get the m alone. Thus, we cancel out the addition by subtracting 2.3 on both sides. This leaves us with the equation $4m=7.4$. In order to cancel out multiplication, we use division, so we divide both sides of the equation by 4 to get that $m=1.85$. We plug 1.85 in for m and confirm that our answer is, indeed, correct.
