-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
3n+18 !
-2n
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
5n = 2n + 3n .
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
That factors to (2n + 1)(n + 2)
3n+18 !
-2n
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
(2n+3)(n+1)=2n2+5n+3.
