7+2n
Add them together. They equal 2n.
That factors to (2n + 1)(n + 2)
2n plus 7 equals 19 2n equals 12 n equals 6
(4n + 1)*(2n + 6) = 8n2 + 26n + 6
7+2n
is eassy
14M + 2n - 6M + 11n = 8M + 13n
Add them together. They equal 2n.
Combine like terms to give 3n + 2
6m + m + m + 4y + n + y + 12 + 2n Group like terms: 6m + m + m + 2n + n + 4y + y + 12 Add: 8m + 3n + 5y + 12
2n + 4m - 2n + m = 5m
2n plus 4 = 2n + 4
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 = 2n + 3n .
Exactly that. 2n+2.
(2n + 7)(2n + 7)
