Solving equationsTo 50
Solve each equation for x.
A two-step equation needs the operations undone in the opposite order to the one they were done in. These free printable worksheets keep every solution a whole number so the method, not the arithmetic, is what is being practiced.
If they get stuck

The answer key prints on a separate page.
3x + 5 = 20 was built by multiplying x by three and then adding five. Undoing it runs backwards: subtract the five first, then divide by three. Children who divide first get 3x + 5 ÷ 3 and an answer that cannot be checked, and the fix is not more practice but the order — last thing done, first thing undone.
Substituting the answer back is the habit worth insisting on, and it costs about five seconds. Put x = 5 into 3x + 5 and see whether 20 comes out. A child who checks their own work stops needing the answer key to find out whether they were right, which is a bigger change than any individual topic.
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
