5n-2+2=4n 5n=4n n=0
n= -2
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
4n + 3 = 19Subtract 3 from each side:4n = 16Divide each side by 4:n = 4
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
The answer is n = 5.
5n-2+2=4n 5n=4n n=0
n= -2
12+4n = 2n12+4n-4n = 2n-4n12 = -2n-1/2(12 = -2n)-6 = n
4n + 3 = 19Subtract 3 from each side:4n = 16Divide each side by 4:n = 4
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7
4n + 5
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
4n/7 + 8 = 20 subtract 8 from each side: 4n/7 = 12 multiply each side by 7: 4n = 84 n = 21
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
it equals -4n
