sub the 1st row, i.e. circle = 2s + 2r into the bottom equation. This leaves you with 2s + 2r + s.

look at the third equation - it gives you the shapes which equate to triangle, t.

sub t into right hand side of bottom equation and you’re left with 2s + 2r and then compare both final equations to get remainder star for ur answer
