kolezko [41]

The system of equations that can be used to determine the number of tetra fish and goldfish purchased is:
x = 2 y. 2 x + 1.5 y = 20

<h3>What are the system of equations ?</h3>

In order to determine the required values, two linear equations would be formed from the question. The two equations would exhibit the relationship between the two types of fishes:

The first equation would show the ratio between the two types of fishes bought: 2y = x

Th second equation would show the total cost of the two type of fish:1.5y + 2x = 20
