Answer:

x= 4

y= -2

Explanation:


-3y+5x=26\\-2y-5x=-16

Solve by using the Elimination Method.


-5y=10\\\\(-5y)/(-5) =(10)/(-5) \\\\y=-2

Now plug y into one of the original equation.

=======================================


-2y-5x=-16


(-2*-2)-5x=-16


4-5x=-16


4-5x+5x=-16+5x


4+16=-16+5x+16


20=5x\\\\(20)/(5) =(5x)/(5) \\\\x=4

=======================================


\left \{ {{x=4} \atop {y=-2}} \right.
