Worked example
5x + 2 = 3x + 10
- Subtract 3x from both sides: 2x + 2 = 10.
- Subtract 2: 2x = 8.
- Divide by 2: x = 4.
- Check both sides: 22 = 22.
Math guide
Bring like terms together before dividing.
Collect variable terms on one side, constants on the other, and recognize identities and contradictions.
Subtract one variable term from both sides, then move the constants. If all variable terms cancel, the remaining statement reveals either an identity or a contradiction.
