Answer:

(2, 4)

Step-by-step explanation:

Let's solve this by elimination through addition and subtraction.  Multiply the second equation by 2.  The resulting system is then:

7y+10x−8=0

4y-10x - 36 = 0

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

11y - 44 = 0, or 11y = 44.  Solving for y, we get y = 4.

Substituting 4 for y in the 2nd equation results in:

2(4) - 5x - 18 = 0, or

-5x  - 10        = 0

Then 5x = -10, or x = 2.

The solution is (2, 4)
