Can some one me i don't know how to solve this question
-4y-11x=36
20= -10x-10y

Hi, thank you for posting your question here at . I could easily help you with this simple Algebra problem particularly system of equations. There are two unknowns (x and y) and two equations, hence this can be solved. 

-4y - 11x = 36
-36 - 11x = 4y
y = (-36 - 11x)/4  <-- equation 1

20 = -10x - 10 y
20+10x = -10y
y = (20+10x)/-10  <--- equation 2

Equating both equations, you could determine x. From there, you could also determine y.

x = -4
y = 2
