Testing Algebra

Now would be a good time for you to test what you have learned. Work out the value of each unknown in the examples below:
  1. y - 4 = 10
  2. 17 - b = 5
  3. 50 - 2a = 30
Hints: Treat b as you would a number. 2a just means "2 lots of a" where a is just a letter used to represent a number.

When you have written down your answers, check them on the next page...
