3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
It is 12n2 + 3n - 58
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
Move the 2n over the equals sign. Become 4n (as 6n-2n= 4n) and then if 4n=16 then n=4.
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
4n
4n + 3y
6n - 2n + 2 = n - 11 4n - n = -11 - 2 3n = -13 n = -13/3 = -4.3333
3n + 4n = 42 7n = 42 n = 42/7 n = 6
3n + 4n = -14 7n /7 = -14 /7 n = -2
2n+2n equals 4n
