Colin gets £x wages each week. After he pays his tax of £t, he then pays his rent of £120. He shares what's left between
himself and his wife. How much do they each get?

They will each get ;

(x-t)/2 - 60

Step-by-step explanation:

Here, we want to know the amount of money that Colin and his wife gets

we start by subtracting the necessary terms

Mathematically, that would be;

x-t-120

So what each of them get will be;

(x-t-120)/2

= (x-t)/2 - 60
