# Solve where πΒ² + πΒ² = π and π + π = π (substituting)

Solve simultaneous equations by substituting a linear equation into a quadratic equation. You need to be confident in solving quadratics by factorisation and by the quadratic formula before starting this lesson. Examples include quadratics of the form πΒ² + πΒ² = π, where r can be a square number.
