Answer:

Your answer is infinitely many solutions

Step-by-step explanation:

To use elimination you have to get one of the variables to be the opposite of each other, so here you would do:

-2(2x+y = 7)

   4x+2y= 14

You multiply the top by -2 to get the opposite of 2y, which is -2y. This in turn multiplies everything by -2 on the top solution giving us the top equation below.

  -4x-2y = -14

+ 4x+2y = 14

--------------------

      0 = 0

If you add those 2 solutions then you get 0 = 0, which is infinitely many solutions

What's the next fraction after 45/60
Darya [45]
You could say 46/60 (both of these fractions can be reduced), but we can find a fraction between 45/60 and 46/60, namely 91/120.  And we can find another between 45/60 and 91/120, and so on ad infinitum.

To answer your question, there is no next fraction.  Infinitely many may be found between any two.
