Simultaneous Equations
Gbogbo ọrọ náà
Solving two linear equations together is familiar ground. Now one of the equations becomes non-linear, perhaps a curve such as a circle or a parabola. Geometrically you are finding where a straight line meets a curve, and there can be two crossing points, one (a tangent) or none.
In this lesson you will learn the reliable substitution method: rearrange the linear equation, substitute it into the non-linear one, and solve the quadratic that results. The classic example, a line meeting a circle, shows the whole process and connects neatly to coordinate geometry.
Ebumnobi
- Solve simultaneous equations in two unknowns by elimination or substitution, including cases with one linear and one non-linear equation.
