9 - 2m/7=19
It is linear equation in m.
9 - 9 - 2m/7 = 19 - 9 [subtracting 9 on both sides]
-2m/7 = 10 [9 -9 = 0 and 19 - 9= 10 ]
7*-2m/7 = 10*7 [multiplying by 7 on both sides]
-2m = 70 [7/7 = 1 and 10*7 = 70]
Dividing by -2 on both sides
-2m/-2 = 70/-2
m = -35
So, the required value of m is - 35.
