A-Level Maths Edexcel (9MA0)

Solve simultaneous equations in two variables by elimination and by substitution, including one linear and one quadratic equation.

This may involve powers of 2 in one unknown or in both unknowns, e.g.
solve:

• $y = 2x+3, y = x^2-4x+8$ or
• $2x-3y = 6, x^2 - y^2 + 3x = 50$
