Worked examples
Solve 3(x + 2) = 12
x = 2
Steps
- Start with 3x + 6 = 12.
- Subtract 6 from both sides: 3x = 6.
- Divide both sides by 3: x = 6 ÷ 3 = 2.
- Check: left side 12, right side 12.
Add 3/4 + 5/6
34 + 56 = 1912
- Mixed number
- 1 7/12
- Decimal
- ≈ 1.583333
Steps
- Common denominator 12: 9/12 + 10/12 = 19/12
Simplify √180
√180 = 6√5
- Decimal
- 13.416408
Steps
- Largest perfect square that divides 180: 36, because 180 = 36 × 5.
- √180 = √36 × √5.
- √36 = 6, so √180 = 6√5.
How the solver works
The solver reads what you type, picks the calculator that fits and fills it in for you. Every answer comes from fixed math rules, the same ones on each calculator page, so the same problem always gets the same answer and steps. If it can’t solve a problem yet, it says so and points you to the calculators.
