Question

Answer 1

1) 4x(x - 5) - (x - 1)(4x - 3) = 5

4x² - 20x - 4x² + 3x + 4x - 3 = 5

-13x - 3 = 5

-13x = 5 + 3

- 13x = 8

x = 8/13

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

x² - 4x - 5x + 20 - x² + 2x - x + 2 = 7

-8x + 22 = 7

-8x = 7 - 22

-8x = -15

x = 15/8

3) (x - 5)(x - 1) = (x - 1)(x - 2)

(x - 5)(x - 1) - (x - 1)(x - 2) = 0

(x - 1)(x - 5 - x + 2) = 0

(x - 1).7 = 0

x - 1 = 0

x = 1

 

Answer 2

4x (x - 5) - (x - 1) (4x - 3) = 5

4x^2 - 20 - x - 1 . 4x - 3 = 5

4x^2 - 24 + 3x = 5
