Thank you for the opportunity to help you with your question!
U r asked to solve for m, which means you have to fi d the value of m that satisfies the given equation. So to do that you have to get all terms containing g m on one side of the equal to sign and the end up with only m on that side and a number on the other side which will be the solution.
10m = 10-5(m-7) distribute the negative sign
10m= 10-5m+35. Add 5m to both sides
10m+5m= 10-5m+35+5m. Simplify by combining like terms
15m= 45. Divide both sides by 15.our solution
m= 3 (answer)
