2x - 5y = 9
2x -9 = 5y
(2x -9) /5 = y
x= -1
(2(-1) -9)/5 =y
(-2 -9) / 5 = y
-11/5 = y
x=0
(0-9)/5 = y
-9/5 = y
x=1
(2(1) - 9) /5 = y
-7/5 = y

Answer:
2/3 cup
Step-by-step explanation:
first you need to convert the fractions so that they have the same denominator (1/3 turns into 2/6)
then you just add up the numerators (2+2=4..... 4/6)
you can stop there or you can simplify it (4/6 turns into 2/3)
 
        
             
        
        
        
Composite numbers are numbers that are not prime.
        
                    
             
        
        
        
we know that
If a ordered pair (x,y) is a solution of the equation, then the ordered pair must satisfy the equation
we have the equation

Let's verify all the cases to determine the solution to the problem.
<u>case A)</u> point 
Substitute the values of x and y in the equation



 -------> is  true
 -------> is  true
therefore
The point   is a solution of the equation
 is a solution of the equation
<u>case B)</u> point 
Substitute the values of x and y in the equation



 -------> is  true
 -------> is  true
therefore
The point   is  a solution of the equation
 is  a solution of the equation
<u>case C)</u> point 
Substitute the values of x and y in the equation



 -------> is not true
 -------> is not true
therefore
The point  is not a solution of the equation
 is not a solution of the equation
<u>case D)</u> point 
Substitute the values of x and y in the equation



 -------> is not true
 -------> is not true
therefore
The point   is not a solution of the equation
 is not a solution of the equation
therefore
<u>the answer is </u>
