Answer:
x = 5
Step-by-step explanation:
Add the equations
x + y = 3
x - y = 7
––––––––
2x = 10
Divide both sides by2
x = 5
Note: for the equations in the question,
none of the given answers are correct.
A
63+43= 106/200= 53%
b
63+21=84/200= 42%
c
84 people live on campus and 63 of them passed 63/84 = 75%
d
yes because the percentage found in part c is much greater than then percentage found in part a

Answer:
Y= 8.
Step-by-step explanation:
If they are directly proportional, we can set up two fractions like this:
We can solve for Y by multiplying both sides by 18, giving us:
Y= 8.
