7 small boxes and 14 large boxes were shipped.
Step-by-step explanation:
Given,
Weight of small box = 50 pounds
Weight of large box = 75 pounds
Total boxes shipped = 21
Weight of shipped boxes = 1400 pounds
Let,
x represent the number of small boxes.
y represent the number of large boxes.
According to given statement;
x+y=21 Eqn 1
50x+75y=1400 Eqn 2
Multiplying Eqn 1 by 50

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 25

Putting y=14 in Eqn 1

7 small boxes and 14 large boxes were shipped.
