1 Linear Equations Learning Outcomes
Changing the subject of a formula (Grade C/A) Solve linear equations (Grade F/E) Solve linear equations with brackets (Grade E) Solve linear equations with unknowns on both sides (Grade D) Set up and solve linear equations (Grade C) Solve simultaneous linear equations (Grade B) Set up and solve simultaneous linear equations (Grade A)

2 Changing the subject of a formula

3 Changing the subject of a formula

4 Rules for changing the subject of a formula
Step 1. FRACTIONS? Remove any fractions by multiplying both sides by the denominator. Step 2. BRACKETS? Expand any brackets. Step 3. NEW SUBJECT ON BOTH SIDES? Collect the new subject on one side of the equals sign. Step 4. MORE THAN ONE OF THE NEW SUBJECT? Simplify or Factorise Step 5. Rearrange to get the new subject on its own.
