Key idea
An equation balances two descriptions
Chike Obi’s work shows how symbols can represent an unknown quantity while preserving equality.
In 8x + 5 = 69, subtracting 5 and dividing by 8 gives x = 8.
Try it yourself
Solve the equation
Solve 8x + 5 = 69.
- Subtract 5 from both sides.
- Divide both sides by 8.
- Substitute the result to check.
Show the answer
x = 8.
Math at work
