-2m+9=7 show steps to answering
To solve the equation -2m + 9 = 7, follow these steps:
1. Subtract 9 from both sides of the equation:
-2m + 9 - 9 = 7 - 9
-2m = -2
2. Divide both sides of the equation by -2 to isolate the variable m:
-2m / -2 = -2 / -2
m = 1
Therefore, the solution to the equation -2m + 9 = 7 is m = 1.
