**Section 1:**

**Chapter 5.3 Simple Fractional Equations**

**Chapter 5.4 Forming Linear Equations to Solve Problems**

**1. Fractional equation: when the variable of an equation is in the denominations of a term, the equation is called fractional equation**

6 /(x – 2) = 3

1/(x + 3) = 2/x

Note: it is important to check the solutions, that they can’t be those values that make a denominator of the original equation zero.

**2. Constructing/Forming Linear Equations to Solve Problems**

Two pages handout of teaching material. The steps involved in problem solving with linear equations are:

- Step 1. Read the question carefully and identify the unknown quantity
- Step 2. Use a letter to represent the unknown quantity (e.g. x)
- Step 3. Express other quantities in terms of x
- Step 4. Construct/Form an equation based on the given information
- Step 5. Solve the equation
- Step 6. Write down the answer statement

**3. Review basic concept of “open parenthesis”**

- 2(3x+y) – 5(0.2x-0.6y) =
- -2(3x+y) + 5(0.2x-0.6y) =
- -2(3x-y) + 5(-0.2x-0.6y) =
- 2(3x-y) – 5(0.2x+0.6y) =
