LEARNING AND PROGRESS PLAN GRADE 3: EQUATIONS By the end of this topic you should be able to. . . Recall how to use the balance method to solve two step equations Solve equations such as 3 x + 4/5 = 2 by balancing both sides of the equation. Solve equations such as 12 - 2 x = 10 by balancing both sides of the equation. Solve the above types of equations when the answers are negative or fractional. Use the balance method to solve equations with unknowns on both sides Notes
