Question
The sum of a number and its half is five less than twice the number. Which of the following equations represents given statement mathematically?
Answer: Option A
:
A
Let the number be 'x'.
Half of the number isx2.
Similarly, twice of the number=2x.
Sum of the number and its half=x+x2
5 less than twice the number=2x−5
Given: Sum of the number and its half is five less than twice of the number.
∴The required equation isx+x2=2x−5
