Answer:

x = 3

Step-by-step explanation:

The fractions need to have common denominators. So, we would make the common denominator (x + 3)(x - 3), or, x^2 - 9

Multiply the numerator by the same number or variable as the denominator and then combine.

Once their is x and a number left you would solve for x.

example: if you had 2 times as many people, then an equivalent ratio would be 18*2 to 4*2 = 36 to 8
