solving equations with bracketsVideo Lesson

Grade 9 Lesson 4 Note

In this lesson you will learn what a linear equation is and what it means to “solve an equation”. In order to solve an equation, we need to complete inverse operations in the reverse BEDMAS order. The solution or root is the value that we get when we solve an equation.

This lesson explains the steps of solving linear equations with brackets. From simplifying the expressions with brackets on both sides of the equal sign; identifying, rearranging and collecting like terms to isolating for the unknown variable by dividing by its coefficient.
