Basic equations
On this page children practise solving simple equations with one unknown — for example 4 × __ = 36 or __ + 57 = 100. Start with the short method and the examples, then use the online practice or print a worksheet with answers.
How to solve this
- A basic equation has a variable (letter or box) on one side; find its value using the inverse operation.
- Keep the equation balanced: whatever you do to one side, do to the other.
- Check by substituting your answer back into the original equation and confirming both sides are equal.
Examples
__ + 47 = 93
46
__ × 6 = 42
