-6n + 2 - 5n = -9
Combine like terms:
-11n + 2 = -9
Subtract 2 from each side:
-11n = -11
Divide both sides by -1:
n = 1

Whatever your value of n is, you need to multiply it by 5 and then add 2 to get your answer. Below is how to solve it algebraically: 5n+2 = 0 (it needs to be equal to something in order to solve it, so I assumed that it equals zero) 5n = -2 n = -2/5
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
(3n+2)(n+1)
3n+2+3n+2=6n+4
