The question
Question: solve 3/(x + 1) = 0.
x is in the bottom of a fraction.
3x + 1 = 0
We write 0 as 0/1.
Now both sides are fractions.
3x + 1 = 01
1 Cross multiply
When two fractions are equal, we can cross multiply.
These two are equal.
3 × 1 = 0 × (x + 1)
Work out the multiplications.
3 = 0
The x parts are gone.
3 = 0 is never true.
So no number works.
There is no solution.
Never true: there is no solution.
Answer
3 = 0
