Gather the m's and n's by rewriting it. 7m - 11n - n + 5m 7m + 5m -11n - n (7m + 5m) + (-11n - n) 12m - 12n ■
5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n
5m-5n+5m+5n When simplified: 10m
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
(4+9)+(5−1242) = −1224 (I assume m stands for metres?)
9m - 14n

5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n
5m−3+8m =5m+−3+8m Combine Like Terms: =5m+−3+8m =(5m+8m)+(−3) =13m+(−3)
5m-5n+5m+5n When simplified: 10m
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
(4+9)+(5−1242) = −1224 (I assume m stands for metres?)
you do some fun then do it
6 - 30m
-7m - 3m + 5m = -5m
4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;
5m - 6 + m + 10 = 6m + 4
