Simultaneous equations can be solved by plotting them on a graph but this can be time consuming. When solving simultaneous equations algebraically, the first step is to try to eliminate one of the ...

Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

SymPy can currently reduce for only one symbol (variable) in an inequality. SymPy can reduce a system containing more than one symbol, if there is only one symbol per inequality. While {func}`~.solve` ...

This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...

Simultaneous equations are two or more equations with two or more variables. They are simultaneous because they can be solved to give values for the variables that are equal in each equation. This is ...
