D) 34/5 because 6(5) = 30 30+4=34 , so its 34/5
        
                    
             
        
        
        
Answer: See below
Step-by-step explanation:
Make a table with first set of numbers as 1,3. Multiply both the numbers of this set sequentially by natural numbers to get the following table
1   2  3  4    5    6     7    8     9      10......
3  6  9  12  15    18   21   24   27    30......
We see that in each set of numbers the 2nd number is 3 times the first number. 
If we plot these sets of numbers on a graph paper, we get a model depicting all the points which satisfy this ration requirement.
 
        
             
        
        
        
(4,10). 
1. There are three ways to solve this: elimination, substitution, graphing.
2. I chose elimination, so I had to get one negative variable and one positive variable of the same value (for example, 18 and -18)
-7x+2y=-8
-16x+9y=26
I chose to get 2y and 9y to equal -18y and 18y. 
So, multiply the first equation by -9. Multiply the second by 2.
63x-18y=72
-32x+18y=52
the 18s cross each other out. So you're left with
63x=72
-32x=52. Add them. 
31x=124, divide both sides by 31, and you'll get 4. 
x=4
Plug your answer for x into one of the equations. Let's use the first one.
-7(4)+2y=-8
-28+2y=-8. add 28 to both sides.
2y=20, divide both sides by 2.
y=10. 
This makes your answer (4,10)
