Inverse Operations
When moving a term to the other side of an equation, the operation is inversed.
To solve for mm, it needs to be alone on one side.
Remove 77 by dividing both sides of the equation by 77.

-9−9 |
7÷77÷7 cancels out |
Check our work
To confirm our answer, substitute m=-9m=−9 to the original equation.
7m7m |

-63−63 |
7(-9)7(−9) |
== |
-63−63 |
Substitute m=-9m=−9 |
-63−63 |
