Multiply the first equation by 2 to get
4x−6y=8 4x - 6y = 8 4x−6y=8Hence solve the simultaneous equations
2x−3y=4 2x - 3y = 4 2x−3y=4 4x−y=13 4x - y = 13 4x−y=13217 exam-style questions on CCEA GCSE Maths Simultaneous Equations. Each one has a worked solution and a mark scheme showing where the marks go.
