Question

solve the equation and find 'x'​

Answer 1

Answer:

doing cross multiplication,

(7x - 2) (5x + 4) = (5x - 1) (7x + 3)

7x (5x + 4) - 2 (5x + 4) = 5x(7x + 3) - 1(7x + 3)

35x² + 28x - 10x - 8 = 35x² + 15x -7x - 3

35x² + 18x - 8 = 35x² + 8x - 3

35x² - 35x² + 18x - 8 = 8x - 3

18x - 8x - 8 = - 3

10x - 8 + 3 = 0

10x - 5 = 0

10x = 5

x = 5/10 = 1/2 = 0.5
