Equations

Bayani Gaba-gaba

An equation says that two expressions are equal, and solving one means finding the value of the unknown that makes the statement true. From a single linear equation to a pair of simultaneous equations to a quadratic, the same balancing idea runs through them all: whatever you do to one side, you do to the other.

In this lesson you will construct and solve linear equations, solve simultaneous equations, and change the subject of a formula. You will also learn how a graphic display calculator solves equations directly, including ones too awkward to rearrange by hand, and at Extended level how to solve fractional and quadratic equations.

Takardar Darasi

Equations are how mathematics answers the question what value makes this true. Pricing, mixing, timing, balancing a budget and modelling motion all come down to setting up an equation and solving it. The skills here, balancing, substituting and rearranging, are among the most reused in the whole syllabus and in every science that follows.
