Key idea

An equation balances two descriptions

Chike Obi’s work shows how symbols can represent an unknown quantity while preserving equality.

Example

In 8x + 5 = 69, subtracting 5 and dividing by 8 gives x = 8.

Try it yourself

Solve the equation

Solve 8x + 5 = 69.

  1. Subtract 5 from both sides.
  2. Divide both sides by 8.
  3. Substitute the result to check.
Show the answer

x = 8.

Math at work

Scientists and astronomers use the same habits

Scientists and astronomers use algebra and functions to plan, compare, test, or communicate decisions. Chike Obi’s work provides a historical example of that connection.
