Combine like terms, 3 and 5, on the right side of the equation.
Distribute 2 to (x + 6) and 3 to (x-4).
Distribute 2 to x on the left side of the equation and 3 to x on the right side of the equation.
Apply the subtraction property of equality to move the 6 from the left side of the equation to the right side.

• before the lesson, students attempt the assessment task individually. you then review students’

solutions and formulate questions that will them improve their work.

• during the lesson, students work collaboratively in pairs or threes, plotting graphs, completing

tables of values and deducing equations. then, based on the number of common solutions,

students link these representations.

• in a follow-up lesson, students receive your comments on the assessment task and use these to

attempt the similar task, approaching it with insights gained from the lesson.
