A) 9 students have dogs.

b) 6 students have cats only

c) 10 students have cats.

From (c) since 10 have cats and 6 have only cats it means 4 students have cats and dogs.

From (a) since 9 students have dogs, and 4 have cats and dogs, it means 5 have only dogs.

Only dogs  + Only cats + both cats and dogs + Neither = Total

5 + 6 + 4 + x = 18

15 + x = 18

x = 18 - 15

x =3

−3x−1x+1=0

2x(x−1)−1(x−1)=0

x=1, x=

2

1

We take the value of x=1

x value put in equation (1)

2(1)+y=3

y=3−2

y=1

x=1

x and y value put (x+y)

x−y
