5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
9 - 5n
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
n=1 2/3
3n + 2n = 25 5n = 25 n = 5
5n + 15 = 25 you subtract 15 from both sides then you get 10 then divided 5n by 10 you get 2n
9 - 5n
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
n=1 2/3
3n + 2n = 25 5n = 25 n = 5
5n = 2n + 3n .
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
Subract 5n from both sides and you get 9=-3n, then divide bother sides by -3 and you get n= -3
That factors to (2n + 1)(n + 2)
3n+18 !
