1. The coefficient is 5
2. The terms are 2x, 4y, and 8
3. The variables are c, cd, d and d
4. The constants are 2 and 14
Answer:
(4,1)
Step-by-step explanation:
x+y=5
x- y=3
Add the equations together to eliminate y
x+y=5
x- y=3
--------------------
2x = 8
Divide each side by 2
2x/2 = 8/2
x = 4
Now we can find y
x+y = 5
4+y = 5
Subtract 4 from each side
4+y-4 = 5-4
y =1
87.5% of 32 questions = 28 questions.
32 - 28 = 4
