Question

5(2x+3)=24+x -10x+15=24-x -10-4x=9-2x

Answer 1

5.(2x + 3) = 24 + x
10x + 15 = 24 + x
10x - x = 24 - 15
9x = 9
x = 9/9
x = 1

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
b)
- 10x + 15 = 24 - x
15 - 24 = - x + 10x
- 24 + 15 = 10x - x
- 9 = 9x
9x = - 9
x = - 9/9
x = - 1

¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨¨
c)

- 10 - 4x = 9 - 2x
- 10 - 9 = - 2x + 4x
- 19 = 2x
2x = - 19
x = - 19/2

Answer 2

5(2x+3)=24+x
10x+15=24+x
10x-x=24-15
9x=9
x=1

-10x+15=24-x
-10x+x=24-15
-9x=9   (-1)
x=-1

-10-4x=9-2x
-4x+2x=10+9
-2x=19   (-1)
x=-19/2
x=-9,5
