That depends what the value of n is.
12n
If n = 7, then 5n + 4 = 5 x 7 + 4 = 39.
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
If 5n + 8 = 43, then n = 7
the answer is 12.12.
(5n + 1)(n + 7)
A - B = -3n + 2 - (5n - 7) = -3n + 2 - 5n + 7 = 9 - 8n
first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
4n
5m-5n+5m+5n When simplified: 10m
1/5n = 7
In the equation 5n-11=4n+20, n is equal to 31.
