I'll do the first one to get you started.

# 1

9m-13%2B3m=11 Start with the given equation.


12m-13=11 Combine like terms on the left side.


12m=11%2B13 Add 13 to both sides.


12m=24 Combine like terms on the right side.


m=%2824%29%2F%2812%29 Divide both sides by 12 to isolate m.


m=2 Reduce.


----------------------------------------------------------------------

Answer:

So the answer is m=2
