We always encounter situations that can be expressed in linear equations. Watch this lesson and learn how to solve linear equations word problems.

Basic concepts: Solving linear equations using multiplication and division, Solving two-step linear equations: $ax + b = c$, ${x \over a} + b = c$, Solving linear equations using distributive property: $a(x + b) = c$, Solving linear equations with variables on both sides,
