ExtremeBDS [4]

Answer:

The system 150x+400y=1950 and x = y+2 could be used to determine the number of small boxes and large boxes ordered where x represents the number of small boxes and y represent the number of large boxes.

Step-by-step explanation:

Given,

Number of nails in small box = 150 nails

Number of nails in large box = 400 nails

Total nails in ordered boxes = 1950 nails

Let,

x be the number of small boxes ordered.

y be the number of large boxes ordered.

According to given statement;

150x+400y=1950          Eqn 1

The contractor bought 2 more small boxes than large boxes

x = y+2                           Eqn 2

The system 150x+400y=1950 and x = y+2 could be used to determine the number of small boxes and large boxes ordered where x represents the number of small boxes and y represent the number of large boxes.
