Answer:
~ 7m-20
Explanation:
~ First, we need to look at like terms and collect them. Like terms are similar numbers like all the m’s can be collected together.
~ Let’s count the number of m’s first. M+m+m+2m+2m should give you 7m.
~ Now lets just count the rest of the numbers: 15+15-30-20. 15+15=30, 30-30=0 and 0-20=-20.
~ Hence you get the answer of 7m-20
