Question

Brian gets £x wages each week. After he pays his tax of £t, he then pays his rent of £155. He shares what's left between himself and his wife. How much do they each get?​

Answer 1

`(1)/(2)(x-t-155)`

Explanation:

Total wages:
`x`

Pays tax
`t`:
`x-t`

Pays rent of 155: 
`x-t-155`

Shares what's left between 2:
`(x-t-155)/(2)`

So each gets:
`(1)/(2)(x-t-155)`
