3m - 2n=-8
m=(-8 - 2n) : 3
m=12/7
12/7 = (-8 - 2n) : 3
12/7 * 3 = -8 - 2n
36/7 = -8 - 2n
36/7 + 8 = 2n
92/7 : 2 = n
46/7 = n
m = (-8 - 2n) : 3
m = (-8 - 2 * 46/7) : 3
m = (-8 - 92/7) : 3
m = -148/7 : 3
m = -148/21
3m - 2n=-8
m=(-8 - 2n) : 3
m=12/7
12/7 = (-8 - 2n) : 3
12/7 * 3 = -8 - 2n
36/7 = -8 - 2n
36/7 + 8 = 2n
92/7 : 2 = n
46/7 = n
m = (-8 - 2n) : 3
m = (-8 - 2 * 46/7) : 3
