Answer 2

Answer:

$2m \: + 7 = 9 \\ 2m = 9 - 7 \\ 2m = 2 \\ m = \frac{2}{2} \\ m = 1 \\ \\ another \: method \\ \\ \\ 2m \: + 7 = 9 \\ divide \: whole \: eqn \: by \: 2 \\ \frac{2m + 7}{2} = \frac{9}{2} \\ \frac{2m}{2} + \frac{7}{2} = \frac{9}{2} \\ m = \frac{9}{2} - \frac{7}{2} \\ m = \frac{9 - 7}{2} \\ m = \frac{2}{2} \\ m = 1$
