6m+13m-7m=108

To solve the equation 6m + 13m - 7m = 108, combine like terms:

6m + 13m - 7m can be simplified to 12m.

So the equation becomes 12m = 108.

To isolate the variable m, divide both sides of the equation by 12:

12m / 12 = 108 / 12.

This simplifies to m = 9.

Therefore, the solution to the equation 6m + 13m - 7m = 108 is m = 9.
