Maths - Basic Algebra - Test

If you have worked through the Revision notes, you will have learnt three methods individually. Now it is time to see whether you can spot which one to use in mixed questions!

Have a look at these questions about manipulating algebra. Simplify the expressions. Put your answers in the box provided.

1. 3x + 4 + 6x + 8 = + 12

2. 5x - 3 - 2x + 7 = 3x +

3. 6a + 3b - 2a + 5c + 4b = + 7b + 5c

4. 5p + 2q - 3p - 5q = 2p -

5. 7x2 + 7x + 3 - 4x + x2 = 8x2 + + 3

6. Rectangle dimensions: 3x + 1 by x + 5

Write an expression for the perimeter of this rectangle. Then simplify your answer.
When you multiply out the brackets you will have: + 12

7. 5(x + 8) = 5x +

8. a(b + c)= ab +

9. p(p - q) = pē -

10. -4(x - 5) = -4x +
