Answer:
(x, y) = (2, 1)
Step-by-step explanation:
The x-coefficients are opposites of each other, so the x variable will be eliminated if the two equations are added.
(x +3y) +(-x -y) = (5) +(-3)
2y = 2
y = 1
Substituting into the first equation gives ...
x +3(1) = 5
x = 2 . . . . . . . subtract 3
The solution is (x, y) = (2, 1).

To answer the question above, determine the ratio between the their typing speed by dividing Jennifer's speed by Paul's. This is shown below,
r = 60 words per minute/ 80 words per minute
r = 3 / 4
Therefore, Paul's typing speed is 3/4 of Jennifer's speed. The answer is letter A.
