Answer:
The length of the blue-and-yellow macaw is 42 in
Step-by-step explanation:
Let
x ----> the length of the toucan in inches
y ----> the length of the blue-and-yellow macaw in inches
we know that

Multiply by 3 both sides to remove the fraction

Divide by 2 both sides

therefore
The length of the blue-and-yellow macaw is 42 in
