The 2 skills that cover it
What a student should be able to do
- Distribute and combine like terms before solving.
- Solve equations with the variable on both sides.
- Recognise equations with no solution or infinitely many solutions.
- Translate multi-step word problems into equations.
- Multiply both sides by the least common denominator to clear fractions.
- Solve equations with fractional coefficients and constants.
- Solve simple proportions as rational equations.
- Check solutions and exclude values that make a denominator zero.
