Question

Can someone please show me how to do these?
My teacher gives me the question and the answer, but I need to show the work/steps.
Thank you!!

x^2 - 9x + 14 / 2x * 4x / x - 2 = 2(x-7)

x+2 / 3x-6 * (6x^2 + 3x -30) = (x+2)(2x+5)

(x^2 - 9 / x +10) / (x+3 / x-4) = (x-3)(x-4) / x + 10

(x^2 - 49 / x + 5) / (x+7) = x -7 / x + 5

(y^2 - y + 2) / (y + 2) = y-3 + 8/y+2
