play basketball?

​

Answer 1

GIVEN :

In a class of $(4y^2 +y-8)$ students (2y +16) play football and the rest play basketball. How many  play basketball?

TO FIND :

The number of students play basket ball

SOLUTION :

Given that in a class there are $(4y^2 +y-8)$ students.

(2y +16) students play football and the rest play basketball.

Now we have to find the number of students play basket ball :

From the given we can write it as  total number of students=students play foot ball and students play basket ball

Let x be the number of students play basket ball.

$(4y^2 +y-8)=(2y+16)+x$

$x=(4y^2 +y-8)-(2y+16)$

$=4y^2+y-8-2y-16$

$=4y^2-y-24$

$x=4y^2-y-24$

⇒ the number of students play basket ball is $4y^2-y-24$

∴ the number of students play basket ball=$4y^2-y-24$
