Rearrange 2x+y=72x + y = 72x+y=7 to make y y\,y the subject.
Hence solve the simultaneous equations
2x+y=7 2x + y = 7 2x+y=7 3x+2y=11 3x + 2y = 11 3x+2y=11217 exam-style questions on CCEA GCSE Maths Simultaneous Equations. Each one has a worked solution and a mark scheme showing where the marks go.
