Question

What is the greatest integer value of y for which 5y - 20 < 0?

Answer 1

5y - 20 < 0...add 20 to both sides
5y < 20...divide both sides by 5
y < 20/5
y < 4 (this states that y is less then 4)

Therefore, the greatest integer that y could be is 3 (because integers cannot be fractions, they have to be whole numbers)

Answer 2

Greatest value of y is 3 .

Explanation:

Given : 5y - 20 < 0.

To find : what is the greatest integer value of y

Solution : We have given that

5y - 20 < 0.

On adding both sides by 20.

5y < 20 .

On dividing by both sides 5.

y < 4.

We can see y is less than 4 , it mean all the values of y must be less than 4 but not including 4 like 3 ,2, 1, 0, -1, -2 ........so on.

So , the greatest value is 3 .

It can not be in fraction because we asked about integer.

Therefore, greatest value of y is 3 .
