X = 4 + (x^2 - 4) / (x - 8)
x(x - 8) = 4(x - 8) + x^2 - 4
x^2 - 8x = 4x - 32 + x^2 - 4
-8x - 4x = -32 - 4
-12x = -36
x = -36/-12
x = 3

Ratio equivalent to 1:6
krok68 [10]
There are many different ratios that are equivalent to 1:6. The way to get an equivalent ratio is to multiple the same integer by the numerator and denominator. So if you multiplied the top and bottom by 2, the ratio would not be 2:12, which is equivalent to 1:6.
