Simultaneous Equations Continued

Simultaneous linear equations can be solved using three different methods: substitution, elimination or using a graph to determine where the two lines intersect.For solving systems of simultaneous equations with linear and non-linear equations, we mostly use the substitution method.Graphical solution is useful for showing where the two equations intersect.

In general, to solve for the values of \(n\) unknown variables requires a system of \(n\) independent equations.

An example of a system of simultaneous equations with one linear equation and one quadratic equation is \begin{align*} y – 2x &= -4\\ x^2 + y &= 4 \end{align*}
