An algebraic expression
5n - 4 = 10n + 6-5n = 10n = -2
10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4
6m + 5n - 4m + 7n = 2m + 12n
14M + 2n - 6M + 11n = 8M + 13n
12m + 3n - 6m + 7n6m + 10n
It is a algebraic expression which can be simplified depending on the plus or minus values of 3n and 10n which have not been given.
An algebraic expression
5n - 4 = 10n + 6-5n = 10n = -2
8m + 3n - 5m + 10n = 3m +13n
10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4
15m + (2n-6m) + 11m = = 15m + 11m + 2n - 6m = 26m - 6m + 2n = 20m + 2n = 2(10m + n)
10n + 3 = 7n + 53n = 2n = 2/3
-1
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
