The equation "9n equals 126" can be written as 9n = 126.
9n + 18 = 81 9n = 63 n = 7
9n+9=81 9n=72 n=8
9n - 9 = 45 9n = 45 + 9 = 54 n = 54 / 9 = 6
it equals -15
The equation "9n equals 126" can be written as 9n = 126.
You need to get n alone.9n=45 → Divide by 9n=45/9n=5
9n + 18 = 81 9n = 63 n = 7
9n+9=81 9n=72 n=8
9n - 9 = 45 9n = 45 + 9 = 54 n = 54 / 9 = 6
it equals -4n
it equals -15
your equation is this 9N=63 9N/9=63/9 N=7 your answer is 7
you have 9n+17=-1 -17 -17 9n=-18 /9 /9 n= -2
n2 + 9n + 18 = (n + 6)(n + 3)
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
If 9n = 36 then we divide both sides by 9 to discover what value n has If we divide 9n by 9 we get n If we divide 36 by 9 we get 4 so, if 9n = 36 the n = 4
