WebWhen solving simultaneous equations (or systems of equations ), several methods can be used such as the substitution method or the elimination method. Another system Cramer's Rule, named after the Swiss mathematician Gabriel Cramer (1704-1752) involves placing the coefficients and constants of each equation into determinants. WebAn example of a system of simultaneous equations is: \begin{align*} x + y & = -1 \\ 3 & = y - 2x \end{align*} We have two independent equations to solve for two unknown variables.
