We have looked at how to solve equations with one unknown value, but what happens when there are two unknown values? An equation with two unknown values will have infinitely many solutions. or \(x=100 ...

Be careful to note what a GCSE question is asking. If it states ‘solve algebraically’ then you must do so. To find solutions from graphs, look for the point where the two graphs cross one another.

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...

This full lesson introduces solving simultaneous equations using graphical methods. The starter is a kinaesthetic activity where pupils order themselves according to the value of the expressions they ...

This is a walk-through of how to solve simultaneous equations where one is linear and the other is quadratic. There is also a starter activity that gets students to practise factorising. Ben Cooper is ...

This document is a tutorial for how to use the Python module sympy to solve simultaneous equations. Since sympy does this so well, there is no need to implement it within reliability, but users may ...

Okay, so I know that as soon as someone tells me what method to use, I'm gonna instantly remember it, but right now, I can think of only 1 way to solve simultaneous equations, and that doesn't work so ...

Differential equations are equations that contain derivatives. The equations are used in calculus to describe relationships among one or more variables. A solution to any series of equations can be ...
