Answer :
In linear equation, 20x + 45y = 440 , y = 2x Where x is the number of small boxes sent and y is the number of large boxes sent.
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
Let be x the number of small boxes sent and y the number of large boxes sent.
Since each small box can hold 20 books (20x), each large box can hold 45 books (45y)and altogether can hold a total of 440 books, we can write the following equation to represent this
20x + 45y = 440
According to the information provided in the exercise, there were 4 times as many large boxes sent as small boxes. This can be represented with this equation
y = 2x
Therefore, the system of equation that be used to determine the number of small boxes sent and the number of large boxes sent, is
20x + 45y = 440
y = 2x
