First step: Isolate the term that has x. To do that, subtract 2y from both sides.
Now divide both sides by 3.

10 small boxes and 11 large boxes were shipped.
Step-by-step explanation:
Given,
Total boxes shipped = 21
Total volume of shipped boxes = 342 cubic feet
Volume of each small box = 10 cubic feet
Volume of each large box = 22 cubic feet
Let,
Number of small boxes = x
Number of large boxes = y
According to given statement;
x+y=21 Eqn 1
10x+22y=342 Eqn 2
Multiplying Eqn 1 by 10
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 12
Putting y=11 in Eqn 1
10 small boxes and 11 large boxes were shipped.

Answer:
Step-by-step explanation:
The points on the straight line are (P, 0) and (0, R).
The slope would be
And , because the y-intercept is at (0, R).
So, the equation of this line would be
Where we multiply the equation by
Therefore, the equation that represents this line is
