Answer:
If 3 students walked, then according to the given ratios, 18 students would have taken the bus.
Step-by-step explanation:
Given: 3 Walkers
1:2 --> 3:6 walkers to subway
1:3 --> 6:18 subway to bus riders
You need to factor the numerator and denominator...
(2x^2+4x-2x-4)/(2x^2-2x-2x+2)
(2x(x+2)-2(x+2))/(2x(x-1)-2(x-1))
((2x-2)(x+2))/((2x-2)(x-1)) so the (2x-2)s cancel out leaving
(x+2)/(x-1)
