Topic: Algebraic Manipulation (Foundation - Unit 3)

Specification References: N5.4 N5.4 Set up and solve simple linear equations.

Candidates should be able to:

• set up simple linear equations
• rearrange simple equations
• solve simple linear equations by using inverse operations or by transforming both sides in the same way
• solve simple linear equations with integer coefficients where the unknown appears on one or both sides of the equation, or with brackets

Notes

Questions in this unit will include geometrical problems, problems set in a functional context and questions requiring a graphical solution.
Questions set without a context will be assessed in Unit 2.

Examples

1. The angles of a triangle are 2x, x + 30 and x + 70. Find the value of x.
   (A diagram would be given.)
