Question

Solve the equation x% of 5x = (x+1) (x-5) / 20​

Answer 1

Answer:

Step-by-step explanation:

Given

x/100 * 5x =  (x+1) (x-5) / 20

  5 x^2      = 100

(x+1) (x-5)      20

5 x^2 = 5 (x+1) (x-5)

5 x^2= 5( x^2 - 5x + x -5)

5 x^2 = 5( x^2 -4x -5)

5 x^2= 5 x^2 - 20x -25

20x = -25

x = - 5/4
