4 + 4n - 12 = 4n - 8
4n + 5
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
(4n + 1)*(2n + 6) = 8n2 + 26n + 6
8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n
n-2m
If 7m = 4n+2 and 7m+2 = 8 m = 6/7 and n = 1
4 + 4n - 12 = 4n - 8
4n + 5
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
It is an expression that can be simplified to -4n-1
-n + 4n = 4n - n = 3n Done!!!!!
5m3 + 4n is an algebraic expression.
15m + 4n - 5m + 9n = 10m + 13n
3 + 3n = 9 + 2n + 4n n = -2
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
4n+13=1 -13 -134n=-12/4 /4n=-3
