� Simple linear equations
One-step and two-step equations. Whole number solutions only.
Practice questions
� Two-step — extending
Larger numbers, negative answers, x on right, decimal solutions.
Practice questions
� Equations — unknowns on both sides
Collect the unknown terms on one side first.
Practice questions
� Equations with brackets
Expand the brackets first, then solve.
Practice questions
� Forming equations — perimeters
Use the perimeter formula to write and solve an equation.
Practice questions
� Forming equations — areas
Use the area formula to write and solve an equation.

Key steps
Golden rule: whatever you do to one side, do to the other.
Two-step: undo addition/subtraction first, then multiplication/division.
Both sides: move the smaller \(x\) term across first.
Brackets: expand first, then solve. Check signs carefully.
Shapes: write the formula, substitute the expressions, simplify, solve.
