m=.449

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