Answer 1

8)

${4x - (3 - 2x)} = 33$

{ 4x -3 +2x } = 33

{ 6x - 3} = 33

6x = 33 + 3

6x= 36

x = 36/6

x = 6

9)

$\frac{x + 3}{2} + \frac{x + 4}{2} = 4$

(x+3+x+4)/2 = 4

x+3+x+4 = 8

2x + 7 = 8

2x + 7 = 8

2x = 8 - 7

2x = 1

x = ½

10)

$x + \frac{x}{2} + \frac{x}{3} + \frac{x}{4} = 3$

x/1 + x/2 + x/3 + x /4 = 3

12x + 6x + 4x + 3x / 12 = 3

25x/12 = 3

25x = 36

x = 36/25
