Solving Linear Equations

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

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

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

3a + 8 = 35 Let’s make this question into a low level 5 question. We know how to solve those! 3a = 35 - 8 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
