Title: Solving Linear Equations


1
Solving Linear Equations
  • Which level would you like to study?
  • Level 5
  • Level 6
  • Level 7
  • Worksheet

2
Level 5
  • Objective Be able to solve linear equations with
    an unknown on one side.

3
Low level 5
  • 4a 24

This means 4 multiplied by a
What is the inverse operation?
6
Division
4
Low Level 5
  • b 3
  • 5

This means b divided by 5
b 3 x 5
What is the inverse operation?
15
Multiplication
5
High Level 5
  • 3a 8 35

Lets 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?
Subtract
Look! A low level 5 question!

6
Level 6
  • Objective Be able to solve linear equations with
    an unknown both sides.

7
Low level 6
  • 5a 3 2a 12

5a 2a 12 - 3
5a 2a 9
Doing this removes the add 3, but remember to
subtract 3 from the other side too!
5a 2a 9
This says add 3
Now, lets remove this.
3a 9
To get rid of our 2a, we have to subtract 2a
What is the inverse operation?
3
Subtract 3

High Level 6
Expanding Brackets Tutorial
  • 5(a - 4) 3(a 2)

5a - 20 3a 6
5a 3a 6 20
First expand the brackets (Click the tutorial
button above if you cannot remember how to do
this)
Now we have a low level 6 question which can be
solved just as before.
5a 3a 26
5a 3a 26
2a 26

Level 7
  • Objective Be able to solve linear equations with
    an unknown on one side, including problems where
    the coefficients are fractional
