Question

a) 5x -3 + x + = 2x +9
b) x + 2x +3 - 5x = 4x - 9

Answer 1

a) 5x -3 + x = 2x +9
5x + x - 2x = +3 +9
8x = 12
x = 12 ÷ 8
x = 1.5

Answer 2

a) 5x -3 + x = 2x + 9

6x - 3 = 2x + 9

6x - 2x = 9 + 3

4x = 12

x= 12/4

x= 3

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

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

- 2x + 3 = 4x - 9

- 2x - 4x = - 9 - 3

- 6x = - 12

x= - 12/-6

x= 2
