Lessons
8Setting Up Equations
Learn to set up equations from problem situations, interpret equations, and use mathematics terminology.
Solving Equations by Inspection
Identify variables, coefficients and constants, use tables to narrow down solutions, and solve equations by inspection.
Solving Equations by Inspection (Continued)
Practise solving equations by inspection, check solutions with inverse operations, and use the balanced-scales idea.
Generating Tables of Ordered Pairs Using Substitution
Use substitution in equations to generate tables of ordered pairs, identify input and output variables, calculate outputs by substitution and inputs by working backwards with inverse operations, and represent relationships in tables, flow diagrams and ordered pairs.
Solving Equations Using Additive and Multiplicative Inverses
Solve equations by applying the additive and multiplicative inverses, simplifying both sides and checking answers.
Solving Exponential Equations Using the Laws of Exponents
Solve exponential equations by making the bases the same and equating the exponents.
