$m=.449$

We need to get m alone. Thus, we cancel out the addition by subtracting 2.4 on both sides. This leaves us with the equation 10m=4.49. In order to cancel out multiplication, we use division, so we divide both sides by 10 to get that m=.449. We plug .449 in for m and confirm that our answer is, indeed, correct.
