Question

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

Answer 1

5x+x-2x=9+3
4x=12
x=12/4
x=3

2x+x-5x-4x=-9
3x-9x=-9
-5x=-9 (-1)
x=9/5
x=1.8

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 + 3 - 5x = 4x - 9

- 2x + 3 = 4x - 9

- 2x - 4x = - 9 - 3

- 6x = - 12

x= - 12/-6

x= 2
