Question

5 X upon 3 X + 4 barabar - 5

Answer 1

$\frac{5x}{3x + 4} = - 5 \\ 5x = - 5(3x + 4) \\ x = \frac{ - 5(3x + 4)}{5} \\ x = - 3x - 4 \\ x + 3x = - 4 \\ 4x = - 4 \\ x = \frac{ - 4}{4} \\ x = - 1$

Answer 2

5x/(3x+4)= -5  ⇒5x=(3x+4)(-5)= -15x-20

                       ⇒5x+15x=-20

                       ⇒20x=-20

                     ⇒x=20/-20= -1  Ans.
