m=6

Step-by-step explanation:

We are given that an equation

9+12m=6+15(m-1)

We have to find the value of m for which prices are the same.

9+12m=6+15m-15

9-6+12m=15m-15

Using subtractive property of equality

3+12m+15=15m

Using addition property of equality

12m+18=15m

18=15m-12m

Using subtractive property of equality

18=3m

$m=\frac{18}{3}=6$

Using division property of equality
