Equations
Akopọ
An equation is a statement that two things are equal, and solving one means finding the value (or values) that make it true. From a single linear equation to a pair of simultaneous equations, the skill of keeping an equation balanced is one of the most powerful in mathematics.
In this lesson you will construct and solve linear equations, solve a pair of simultaneous linear equations, and change the subject of a formula. (At Extended these skills extend to fractional, simultaneous non-linear and quadratic equations.)
