Answer 1

-16 - 4m + 5m = 14 - 5m

−16−4m+5m=14−5m

−16+−4m+5m=14+−5m

(−4m+5m)+(−16)=−5m+14

m+−16=−5m+14

m−16=−5m+14

m−16+5m=−5m+14+5m

6m−16=14

6m−16+16=14+16

6m=30

6m/6=30/6

m=5

15 + 2n + 3n - 7 = 4n + 7

15+2n+3n−7=4n+7

15+2n+3n+−7=4n+7

(2n+3n)+(15+−7)=4n+7

5n+8=4n+7

5n+8=4n+7

5n+8−4n=4n+7−4n

n+8=7

n+8−8=7−8

n=−1
