Question 1024379
The question 
-14=-20y-7x
10y+4=2x
----------  That's not a question.  It's 2 equations.

My attempt 
-20y-7=-14 ****** What happened to the x?  (That's a question.)
10y-2x=-4 (×2)

-20y-7x=-4 *********** Why did -14 become -4 ?
20y-4x=-8
-11x=-12

This i know is wing but help me figure out how to do this correctly please
