Question

(×-5) (×+3)=(×-7)(×+4) solve the equation please help me​

Answer 1

Answer:

-13

Step-by-step explanation:

      (×-5) (×+3)=(×-7)(×+4)

or,  (x² + 3x) + ( -5x - 15) = (x² + 4x) + ( -7x - 28)

or,  x² - 2x - 15 = x²  - 3x - 28

or, -2x + 3x = -28  + 15 ( x cancels out from both sides of the equation)

or, x = -13
