Step-by-step explanation:

The relationship is proportional when the ratio of y to x is the same for all table entries. In selection D, that ratio is ...

12/-3 = 24/-6 = 36/-9 = -4

Determine this one algebraically

Answers

Answer:

x = 5

y = 5

Step-by-step explanation:

In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...

2x - x = 5

1x = 5

x = 5

Now we plug that value of x into the second equation

4x - 2y = 10

4(5) - 2y = 10

20 - 2y = 10

-2y = -10

y = 5

Finally, we can see that both x and y have a value of 5.
