Question

solve the equation 2m-7=9

Answer 1

Answer:

2m = 9 +7

= 2m = 16

= m = 16/2

= m= 8

Answer 2

Answer:

Given equation,

2m + 7 = 9

Subtracting 7 from both the sides, we have

2m + 7 – 7 = 9 – 7

2m = 2

Now, dividing by 2 on both sides, we have

2m/2 = 2/2

m = 1

Thus, m = 1 is the solution of the given equation.
