It is: 9m +8 -4m +7 -5m = 15
15m + 4n - 5m + 9n = 10m + 13n
3+4m+5m=214m+5m=21-39m=18m=18/9m=2
4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;
It can be simplified to: 9m-2n
5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n
you do some fun then do it
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
It is: 9m +8 -4m +7 -5m = 15
8m + 3n - 5m + 10n = 3m +13n
15m + 4n - 5m + 9n = 10m + 13n
3+4m+5m=214m+5m=21-39m=18m=18/9m=2
4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;
2n + 4m - 2n + m = 5m
4m+9+5m-12=42 9m=45 m=5
(4+9)+(5−1242) = −1224 (I assume m stands for metres?)
