Answer:

x = 6

y = -7

Step-by-step explanation:

4x+2y = 10

x - y = 13

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

4x + 2y = 10

-4[x - y = 13]

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

4x + 2y = 10

-4x + 4y = -52

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

6y = -42

y = -7

Now that we have y, plug in the value to solve for x:

4x + 2(-7) = 10

4x - 14 = 10

4x = 24

x = 6
