Solve the system of equations 2 + 2y = -20 and x + 3y = -27 by combining the
equations.

no estoy segura como se debe responder

1 (x + 2y = -20) > x*2y= -20

-1 (x + 3y = -27) > x-3y= 27

          (0) x + (-1) y = 7

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2
