1. Solving Linear Equations

2. Objective: Be able to solve linear equations with an unknown on one side.

3. 4a = 24 a = 24 4 = 6 This means “4 multiplied by a”
What is the inverse operation?
= 6
Division

4. b = 3 5 b = 3 x 5 = 15 This means “b divided by 5”
What is the inverse operation?
= 15
Multiplication

5. 3a + 8 = 35
Let’s make this question into a low level 5 question. We know how to solve those!
3a =
This is the only bit that is different. We can use inverse operations to get rid of it.
This says “add 8”
3a = 27
What is the inverse operation?
a = 27 3
Subtract
= 9
