Question is asking about which shows the equation 
in general form. Options are not given but we can still find the solution.
Given equation is a linear equation so we will need to check general formula of the equation of line. which is given by formula:
Where a, b and c are integers.
Now compare given equation with general formula to find the difference between them.
We see that every term is on the left side of the = in formula but 480 is on the right side of give equation so we will move 480 to the left side.
to do that we subtract 480 from both sides
Now the new equation looks exactly like the general formula.
Hence final answer is
Answer:
If I'm thinking right then the answer should be 5% ?
There's 8 students total if I'm correct?
2 people got 15.
2 people got 16.
1 person got 17.
2+2+1=5
2 person got 14.
1 person got 12.
2+1=3 There's 8 students total. but the answer should be 5%.
34% of 150 is 51.
I hope this helps.
5x + 3y = 7> (4) 5x + (4) 3y = (4) 7
4x + 5y = 3> (-5) 4x + (-5) 5y = (-5) 3
20y + 12y = 28
-20x -25y = -15
(X's cross out) 12y - 25y = 28 -15
-13y = 13
Y = -1
(Plug in for y) 5x + 3(-1) = 7
5x -3 =7 (add 3 to 7)
5x = 10 (divide by 5)
X= 2
Ordered Pair= (2, -1)
