When m is 7, (6m + 3) is (42 + 3) = 45.(45)3 = 91,125
6m + 5n - 4m + 7n = 2m + 12n
14M + 2n - 6M + 11n = 8M + 13n
2m + 13n
6m + m + m + 4y + n + y + 12 + 2n Group like terms: 6m + m + m + 2n + n + 4y + y + 12 Add: 8m + 3n + 5y + 12
When m is 7, (6m + 3) is (42 + 3) = 45.(45)3 = 91,125
6m + 15 = 12 Subtract 15 from both sides: 6m = -3 Divide both sides by 6: m = -3/6 = -1/2
12m + 3n - 6m + 7n6m + 10n
15m + (2n-6m) + 11m = = 15m + 11m + 2n - 6m = 26m - 6m + 2n = 20m + 2n = 2(10m + n)
6m + 5n - 4m + 7n = 2m + 12n
14M + 2n - 6M + 11n = 8M + 13n
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
-7 + 4 = -3. So -3 = 6m - 5. Add 5 to both sides of the equation and you get 2 = 6m. Divide both sides of the equation by 6 and you get 2/6 = m. This simplified to, m = 1/3.
8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n
-8 + (5m - 6m) = -8 + (-m) = -8 - m
2m + 13n
6m + m + m + 4y + n + y + 12 + 2n Group like terms: 6m + m + m + 2n + n + 4y + y + 12 Add: 8m + 3n + 5y + 12
