You cannot solve 2n-11 -23 because it does not have the equal signs. The question can be simplified into: 2n-34.
It can be simplified to: 9m-2n
5-2n=3 -2n=3-5 -2n=-2 n=1
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
Solve for n. 2n+3=0 2n=-3 n=-3/2
You cannot solve 2n-11 -23 because it does not have the equal signs. The question can be simplified into: 2n-34.
It can be simplified to: 9m-2n
4n+20=53-2n
5-2n=3 -2n=3-5 -2n=-2 n=1
3n - 2n = n 3n - 2n = (3 - 2)n = 1n = n
10 - 2n = 30 10 - 2n + 10 = 30 + 10 2n = 40 2n/2 = 40/2 n = 20
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
You can't. 17 + 2n = 21 + 2n gives: 2n = 4 + 2n which gives 0=4 which is not possible so the sum is not solveable.
5n+6n-2n can be solved by combining like terms. Combine 5n and 6n and -2n to get 9n.
-6n-2n 16 can be solved mathematically getting n = - 2.
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
