Solving equationsTo 50
Solve each equation for x.
3x = 21 and x ÷ 4 = 3 are solved in a single move: undo the multiplying or dividing that ties x down. These free printable worksheets keep to that one step, with a whole-number answer every time.

The answer key prints on a separate page.
3x means three times x, so it comes apart by dividing both sides by three — x = 7. x ÷ 4 = 3 is the mirror: x was divided by four, so multiply both sides by four to get x = 12. Both are the same idea, an inverse operation applied to both sides, and meeting them together is what stops a child from reaching for subtraction out of habit.
This is the multiplication-and-division half of one-step equations, kept apart from the addition-and-subtraction half so the coefficient form 3x = 21 gets its own attention — it is the one that later two-step and both-sides work is built on. Every equation is made backward from a positive whole-number solution, so a child can always check by substituting it back. Because each answer is a single number, these sheets also play on the practice page.
