Equation Problems

Equation problems turn words into algebra. In NSW Year 8 maths (NESA outcome MA4‑EQU‑C‑01) you name the unknown with a pronumeral, write every other amount in terms of it, form an equation, solve it, and then answer the question in a sentence with units.

You will solve number puzzles, problems about consecutive and consecutive even numbers, ages, perimeters and sharing the money raised at a car wash, and substitute into formulas such as a phone battery's charge after \(h\) hours. When two amounts are compared, such as two gym memberships, the pronumeral ends up on both sides. Each answer is checked against the words of the problem. It is part of Year 8 Equations.
