Answer:
x = 3.53 ( this may not be the exact number because my factoring is rusty)
Step-by-step explanation:
7x/(7x + 3) = (20x - 4)/(22x - 2)
7x(22x - 2) = (20x - 4)(7x + 3)
154x² - 14x = 140x² + 60x -28x -12
combine like terms & reduce:
14x² -46x - 12 = 0
divide by 2 to simplify:
7x² - 23x - 6 = 0
factor:
(7x + 1.7)(x - 3.53) = 0
x = 3.53
