You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes [tex] \frac{20}{24} m- \frac{10}{24} = \frac{21}{24} m+ \frac{16}{24} [/tex] subtract 16/24 to both sides and you get [tex] \frac{20}{24} m- \frac{26}{24} = \frac{21}{24} m [/tex] now subtract 20/24 from both sides and [tex] \frac{-26}{24} = \frac{21}{24} m[/tex] multiply 24 on both sides -26=21m and divide by 21 on both sides m=-26/21 or -1.24
