In this section, we will look at linear equation questions which involve two kinds of operations: addition and subtraction. We will deal with two-step linear equations modeled by diagrams as a start. Then, we will learn how to solve algebraic equations and related word problems.

Basic Concepts: Understanding integer division, Model and solve one-step linear equations: $ax = b$, $\frac{x}{a} = b$

Related 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

- 1.Find x in the equation modelled by each diagram.a)

b)

- 2.Find x in the equation modelled by algebra tiles.a)

b)

- 3.Solve.a)$7x + 9 = 21$b)$98 - 2x = 14$c)$- 35 = 6x + 49$d)$- 4x - 11 = 109$
- 4.The total admission fee of an aquarium for 30 students is $240 after a group discount of $3 for each person. What is the original admission fee before the discount?
