You need to get n alone.9n=45 → Divide by 9n=45/9n=5
7x + 3y=63
9n + n = 10n
Not until it equals something. Equations have equals signs.
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
9n + 18 = 81 9n = 63 n = 7
3 squared is 9 and so 9n = 63 which means n = 7
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+9=81 9n=72 n=8
12
9n - 9 = 45 9n = 45 + 9 = 54 n = 54 / 9 = 6
it equals -4n
it equals -15
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
