Step 1: Divide by 5 on both sides ÷5
5x means 5 × x. Divide both sides by 5 to get x on its own.
x = 2x is on its own. x = 2.
Multiplying is undone by dividing.
Answer: x = 2
Check it
Put x = 2 back into the question. If both sides come to the same number, the answer is right.
Left side: 5x → 10
Right side: 10 → 10
✓ Both sides are 10, so x = 2 is right.
