Question

4(x+1)-ax=x+5 solve for x

Answer 1

`4(x+1)-ax=x+5`


`4x+4-ax=x+5`
`Expand`


`4x-ax=x+5-4`
`Subtract \ 4 \ from \ both \ sides`


`4x-ax=x+1`


`4x=x+1+ax`
`Add \ ax \ to \ both \ sides`


`4x-x=1+ax`
`Subtract \ x \ from \ both \ sides`


`3x=1+ax`


`3x-ax=1`
`Subtract \ ax \ from \ both \ sides`


`x(3-a)=1`


`x= (1)/(3-a)`

Answer 2

4(x + 1) - ax = x + 5
4(x) + 4(1) - ax = x + 5
4x + 4 - ax = x + 5
- x - x
3x + 4 - ax = 5
- 4 - 4
3x - ax = 1
x(3) - x(a) = 1
x(3 - a) = 1
3 - a 3 - a
x = 1/(3 - a)
