Hi again Travina;

x=angle fish

2x=guppies

27=x+2x

27=3x

Let's divide both sides by 3...

27/3=(3x)/3

9=x

9 angle fish

2(9)=18 guppies

Let G be the number of guppies bought

Let A be the number of angle fish

so,

G + A = 27 eq. 1

G = 2A eq. 2

subsitute eq. 2 into eq. 1

2A + A = 27

3A = 27

divide both sides by 3:

A = 9

so she bought 9 angle fish.

since G = 2A, the number of guppies she bought is 2(9) or 18

therefore she bought

**18 guppies and 9 angle fish.**
