Answer 1

g) x=4 h) x=2 i) x= -3  j)x=7  

Answer 2

     G

7x-2+4 = 10+5x

7x - 5x = 10 + 2 - 4

2x = 8

x = 8/2

x = 4

       H

X+2x+3-5x = 4x-9

x + 2x - 5x - 4x = 9 - 3

3x - 9x = 6

-6x = 6

x = -6/6

x = - 1

       J

3x-2 = 4x-9

3x - 4x = - 9 + 2

-1x = - 7

x = -7/-1

x = 7

       K

(x-3)-(x+2)+2) (x-1) -5 =0

(x² - 2x + 3x - 6 + 2)(x-1) - 5 = 0

x² - 2x² + 2x + 3x² - 3x - 6x + 6 - 2x - 2 - 5 = 0

x² - 2x² + 3x² + 2x -3x - 6x - 2x + 6 - 2 - 5 = 0

2x² + - 9x - 1 = 0

Δ = (-9) - 4.(2).(-1)

Δ = 81 + 8

Δ = 89
