See a solution process below:

Explanation:

Step 1) Subtract color(red)(1) from each side of the equation to isolate the m term while keeping the equation balanced:

-color(red)(1) + 9 = -color(red)(1) + 1 + m/7

8 = 0 + m/7

8 = m/7

Step 2) Multiply each side of the equation by color(red)(7) to solve for m while keeping the equation balanced:

color(red)(7) xx 8 = color(red)(7) xx m/7

56 = cancel(color(red)(7)) xx m/color(red)(cancel(color(black)(7)))

56 = m

m = 56

56

Explanation:

9=1+m/7

9-1=m/7

8=m/7

8*7=m

m=56
