18.2 Solving twostep linear equations using addition and subtraction: $ax + b = c$
Solving twostep linear equations using addition and subtraction: $ax + b = c$
In this section, we will look at linear equation questions which involve two kinds of operations: addition and subtraction. We will deal with twostep linear equations modeled by diagrams as a start. Then, we will learn how to solve algebraic equations and related word problems.
Lessons
