14M + 2n - 6M + 11n = 8M + 13n

(2m + 1)(8m + 9)

8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n

8m-48

8m + 3n - 5m + 10n = 3m +13n

Without an equality sign it has no solutions but as an algebraic expression it can be simplified depending on the plus or minus values of 8m and 2m

8m + 7 = -98m = -16m = -2

It cannot be simplified any further so it is: 8m + 10

If: 8m = 32m+96 Then: m = -4

8m

The GCF is 8. 8(m + n)

If you mean: -8m+14m-8 then the given expression can be simplified to 6m-8
