In the past articles, I have shown the readers how to solve 2 linear equations using substitution method and linear combination method. In the next few articles, I will show you that the same methods ...

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 ...

Learn how to solve a system of equations by substitution. To solve a system of equations means to obtain a common values of the variables that makes each of the equation in the system true. To solve a ...

A system of simultaneous equations is a set of two or more equations that share the same variables. We solve the equations by finding a common set of values of the variables which solve all the ...

The conventional approach to solve 2x2 equations in linear algebra involves elimination/substitution. However, the method that I will be demonstrating in this essay ...

Simultaneous equations are two linear equations that can be solved using bar models. By remembering that the same letter will always have the same value we can work out the missing values. To solve ...
