24-6= 18
18 pens

Answer 2

number of pens bought by John = 15

Explanation:

John bought 24 pens and pencils. There were 6 more pens than pencils.

LEt x be the number of pens

and y be the number of pencils

John bought 24 pens and pencils. so x+y = 24 (equation 1)

There were 6 more pens than pencils.

pens= 6 more than pencils

x= y+6 (equation 2)

Now we solve for x and y

Substitute equaton 2 in equation 1

x+ y =24

y+6+y = 24

2y+6 = 24

subtract 6 from both sides

2y = 18 ( divide by 2)

y=9

x= y+ 6 (plug in y =9)

x= 9+6 = 15

So number of pens bought by John = 15
