5n + 6n - 2n
That factors to (2n + 1)(n + 2)
2n/5 or 2/5n
-2
5n + 12 = 3n Try to get all expressions with n on the left side 5n + 12 - 3n = 3n - 3n 2n + 12 = 0 Try to get rid of 12 on the left side 2n + 12 - 12 = -12 2n = -12 n = -12/2 = -6
6+5n=2n-9Isolate the variable by subtracting 2n and 6 from both sides.5n-2n=-9-63n=-15n=-5
5n + 6n - 2n
9 - 5n
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
5n + 1 = 10 + 2n5n - 2n + 1 - 1 = 10 - 1 + 2n - 2n3n = 93n/3 = 9/3n = 3
Subract 5n from both sides and you get 9=-3n, then divide bother sides by -3 and you get n= -3
9+2n=5n this is how you would set up the problem 9+2n-2n=5n-2n then you subtract the number with the variable on each side 9=3n this is what it leaves you with 9/3=3n/3 then you divide three by both sides to get the variable by itself 3=n then you have your answer Hope this helps you!!
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
5n - 9 = 2n + 6 : Add 9 to both sides 5n = 2n + 15 : Subtract 2n from both sides 3n = 15 : Divide both sides by 3 n = 5
5n = 2n + 3n .
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
3n+18 !
