Question

(9x - 7)(x + 6) = (3x - 4)(3x + 5)​

Answer 1

Answer:

$(9x - 7)(x + 6) = (3x - 4)(3x + 5)$

$9x(x + 6) - 7(x + 6) = 3x(3x + 5) - 4(3x + 5)$

${9x}^{2} + 54x - 7x - 42 = {9x}^{2} + 15x - 12x - 20$

${9x}^{2} - {9x}^{2} + 47x - 42 = 3x - 20$

$47x - 3x = 42 - 20$

$44x = 22$

x = 22/44

x = 1/2

Ans. 1/2

Hope it helps.
