*With explanation*​

Answer 1

Answer:

m=3

Step-by-step explanation:

7m-8=2m+7

7m-2m=7+8

5m=15

m=15/5

m=3

Answer 2

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.
