Answer 1

Hi...☺

Here is your answer...✌
=================================

Let the number be x

According to the question,

$\frac{5}{2} x - 7 = \frac{11}{2} \\ \\ \frac{5x}{2} = \frac{11}{2} + 7 \\ \\ \frac{5x}{2} = \frac{11 + 14}{2} = \frac{25}{2} \\ \\ = > 5x = 25 \\ \\ = > x = 5$
Hence the number is 5

Answer 2

let the number be x
According to the given question,
5x/2-7=11/2
5x-14/2= 11/2
5x=25
x=5
Hence the required number is 5.
