One-step equations
Solve x/4 = 7
The aim is to get x on its own. Whatever we do to one side, we do to the other, so the equation stays balanced. This one takes 1 step.
- x/4 = 7The question.

Step 1: Multiply by 4 on both sides ×4
x/4 means x is divided by 4. Multiply both sides by 4.
x = 28x is on its own. x = 28.
Dividing is undone by multiplying.
Answer: x = 28
Check it
Put x = 28 back into the question. If both sides come to the same number, the answer is right.
Left side: x/4 → 7
Right side: 7 → 7
✓ Both sides are 7, so x = 28 is right.
