प्रश्न
Find a number such that when 5 is subtracted from 5 times the number, the result is 4 more than twice the number.
उत्तर
Let the number be x.
According to the question,
\[5x - 5 = 2x + 4\]
\[\text{ or }5x - 2x = 4 + 5\]
\[\text{ or }3x = 9\]
\[\text{ or }x = \frac{9}{3}\]
or x = 3
Thus, the number is 3.
