# Linear Equations part 2

**Watch the video below then write the notes and do the worksheet**

### Date: May 18, 2020

### Subject: Mathematics

### Topic: Linear Equations

**As we discovered in our last lesson an Equation is a number sentence joined by an equal sign and the expression on the left is equal to the expression on the right. **

### An algebraic equation is one in which the equation has a letter symbol in place of a number on one or both sides of the equation.

### In this lesson we will learn to solve an equation that uses addition, subtraction, multiplication and division.

### a + 3 = 10

### In this equation we are adding so in order to find the value of a we subtract 3 from both sides.

### b – 4 = 8

### In this equation we are subtracting so in order to find the value of b we add 4 to both sides.

### 5y = 25

### In this equation we are multiplying so in order to find y we divide both sides by 5

### x/2 = 4

### In this equation we are dividing so in order to find x we multiply both sides by 2
