7m-8=2m+7
So subracting 2m from both the sides.
=> 7m-2m-8=2m-2m+7
=>5m-8=7
Adding 8 to both the sides.
=>5m-8+8=7+8
=>5m=15
Dividing both the sides by 5.
=>5m/5=15/5
=>m=3
For verification of answer put m=3 in the given equation.
=>7(3)-8=2(3)+7
=>21-8=6+7
=>13=13
It is true.
=>m=3 is a root/solution/zero of the equation.
Hope it is helpful.
