A one-line explanation under the Resultado tells what the current step represents.
What does this Saída mean?
Multiply both sides by the LCM of denominators to turn coefficients into integers. The LCM is shown inside the log for fraction-heavy examples.
We remove x terms, move constants, and divide by the coefficient, always phrasing it as “do the same to both sides” to reduce sign mistakes.
When there is a unique solution, the value of x is substituted back into the original equation to show that both sides match.
Perguntas frequentes
Por que applying the same operation keep the equation true?
Adding, subtracting, multiplying, or dividing both sides by the same value keeps the equality intact. The step log makes this visible.
How is this different from “transposing”?
Instead of flipping signs when moving terms, every step is a mirrored operation on both sides, which is safer with fractions or parentheses.
How do you clear denominators?
We Calcular the LCM of denominators and multiply both sides to make coefficients integers. The chosen LCM appears in the steps.
Are parentheses and implicit multiplication supported?
Yes. Entradas like 2x, 3(x-2), and (x+1)2 are normalized before solving.
How do you detect no solution or infinite solutions?
If the x coefficient becomes 0 and constants disagree, it is no solution; if they match, it is infinite solutions. Both are highlighted.
