Question:

In a class of (4y + y - 8) students, 2y + 16 play

football and the rest play basketball. How many

play basketball ?

(a) 4y2 + 3y - 24 (b) 4y2 - y - 24

(c) 4y2-y + 8

(d) 4y2 – y + 24

Answer:

We need to subtract (2y + 16) from (4y + y - 8)

$(4y + y - 8) - (2y + 16)$

$5y - 8 - 2y - 16$

$5y - 2y - 16 - 8$

$3y - 24$

No of students playing basketball are 3y-24
