Begin with simple equations and inequalities and build up to more complex equations. Challenge students to justify each step of solving an equationor inequality. Transforming 2 x- 5 = 7 to 2x=12 is possible because 5 = 5, so adding the same quantity to both sides of an equation makes the resulting equation true as well.Review for Grade 9 Math Exam - Unit 6 - Linear Equations and Inequalities Answer Section MULTIPLE CHOICE 1.
