Answer: (1,2)

Step-by-step explanation:

I will help you..

Given:

-2x-5y=-12\\10x-4y=2

Lets cancel out the x term..

5(-2x-5y)=-12(5)\\=-10x-25y=-60

Now our system looks like this:

-10x-25y=-60\\10x-4y=2

Add.

-29y=-58\\y=2

plug in 2 for y

-2x-5(2)=-12\\-2x-10=-12\\-2x=-2\\x=1

Therefore the system is:

(1, 2)

If this helped consider marking brainiest.
