Make b the subject of the formula.

Do square root(b) = a - 6, and then square both sides.

Assuming the square root is just over the b (and not over the b+6) then this is the correct starting point.

It’s over b and 6
Sorry if I didn’t make it clear
Couldn’t find a longer square root 😂

So it's a=b+6a = \sqrt{b + 6} ?

If you don't know Latex formatting, use brackets as suggested above :smile:

Have you solved it now?
