Linear equations

Solve linear equations with unknowns on both sides, brackets, and fractional coefficients

What you'll learn

  1. 1

    A linear equation is like a seesaw that stays balanced. Whatever you do to one side, you must do to the other!

  2. 2

    If you add 3 to the left side of a balanced equation, what must you do to the right side?

  3. 3

    Let's solve x + 5 = 12 together.

  4. 4

    Solve x + 3 = 8 using the number line. Start at 8 and jump back 3 to find x.

  5. 5

    What is the solution to x + 7 = 15?

  6. 6

    Now try 2x = 10. This is like '2 times something equals 10'.

  7. 7

    Solve 3x = 21. What is x?
