Words to remember

equation - a number sentence with an equals (=) sign. For example: 2a + 5 = 11

LHS - abbreviation for the left hand side of an equation – the LHS of the above equation is 2a + 5

RHS - abbreviation for the right hand side of an equation – the RHS of the above equation is 11

pronumeral - A letter (or combination of letters) used as a placeholder for a number (or many possible numbers).

E.g. In 2x + 5, x is the pronumeral.

Linear equation - a linear equation is a relationship between variables which produces a straight line when plotted.

Resources to help with this concept

Spirit of Math

The annotation in this video is a little different to our module but you if you like the way they show flow charts here then it's ok to use this method instead!

Maths is Fun

Interactive equation balance.

Better than your Prof

A really clear video on how graph linear equations. Note that they use the pronumeral "b" to represent the y-intercept, we usually use "c" in Australia but it's the same thing.
