-15/7…………………………………………………..
Answer:
a=-13
Step-by-step explanation:
16−5a+2a−1=41−a
16-1-41 = 5a-2a-a
-26 = 2a
a= -26/2
a=-13
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
