He has £160 out of £400 saved up. Just rewrite that as a fraction and then there are two ways to finish it off.

First we swap our x and y variable, so we get
x = 3y + 2
Then, we solve for y
We can first subtract 2 on both sides
x - 2 = 3y
Then we can divide by 3 on both sides to get
x/3 - 2/3 = y
So our final equation is
y = x/3 - 2/3
