Answer:$2.10
Step-by-step explanation:
In this problem, we just substitute the given n equal to -2, 0 and 1 to th given equation m + 3x = 7 to find m.
m = 7 - 3n 1. m = 7 - 3*-2 = 7 + 6 = 132. m = 7 - 3*0 = 73. m = 7 - 3*1 = 7-3 = 4

![\frac{5}{15}+ \frac{9}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B15%7D%2B%20%5Cfrac%7B9%7D%7B15%7D)
Since the denominators are equal to, its going to be combine by the fraction.
![\frac{5+9}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B5%2B9%7D%7B15%7D)
Finally add by the numbers.
![9+5=14](https://tex.z-dn.net/?f=9%2B5%3D14)
Final answer: ![\boxed{=14/15}](https://tex.z-dn.net/?f=%5Cboxed%7B%3D14%2F15%7D)
Hope this helps!
