If you know that n = 15, substitute 15 for n and solve: n + 3 - 9 15 + 3 - 9 9
3 + 3n = 9 + 2n + 4n n = -2
9
10n + 3 = 93 Therefore, 10n = 90 n = 90/10 n = 9
Yes it does. Very good !
N=3
If you know that n = 15, substitute 15 for n and solve: n + 3 - 9 15 + 3 - 9 9
3 + 3n = 9 + 2n + 4n n = -2
6n -3=2n+9 6n-2n=9+3 4n=12 n=12/4 n=3
9
10n + 3 = 93 Therefore, 10n = 90 n = 90/10 n = 9
Yes it does. Very good !
n + 9 = 4747 - 9 = nTherefore n = 38.
N=0
2+3 = 5 * 2 = 10. 7+2 = 9 * 7 = 63.6+5 = 11 * 6 = 66.x+y = z * x = n.9+7 = 16 * 9 = 144
Subract 5n from both sides and you get 9=-3n, then divide bother sides by -3 and you get n= -3
