(7x+3)/(7x-3)=(5x+4)/(5x-4)
Answers
Step-by-step explanation:
We have, (7x – 2) / (5x – 1) = (7x +3)/(5x + 4) (7x – 2) / (5x – 1) – (7x +3)/(5x + 4) = 0 By taking LCM as (5x – 1) (5x + 4) ((7x-2) (5x+4) – (7x+3)(5x-1)) / (5x – 1) (5x + 4) = 0 By cross-multiplying we get, (7x-2) (5x+4) – (7x+3)(5x-1) = 0 Upon simplification, 35x2 + 28x – 10x – 8 – 35x2 + 7x – 15x + 3 = 0 10x – 5 = 0 10x = 5 x = 5/10 = 1/2 Now let us verify the given equation, (7x – 2) / (5x – 1) = (7x +3)/(5x + 4) By substituting the value of ‘x’ we get, (7(1/2) – 2) / (5(1/2) – 1) = (7(1/2) + 3) /(5(1/2) + 4) (7/2 – 2) / (5/2 – 1) = (7/2 + 3) / (5/2 + 4) ((7-4)/2) / ((5-2)/2) = ((7+6)/2) / ((5+8)/2) (3/2) / (3/2) = (13/2) / (13/2) 1 = 1Read more on Sarthaks.com - https://www.sarthaks.com/665130/solve-the-equationand-verify-your-answer-7x-2-5x-1-7x-3-5x-4
