Answer: x+5y=-13= (x=−5y−13)
2x-5y=-20= (x=5/2y-10)
Step-by-step explanation: The answers are labeled in parenthesis. According to my calculations, this is what I got. Sorry for any inconvenience.
Answer:
x+5y=-13 ......(1)
2x-5y=-20..........(2)
adding equation 1 and 2
x+5y+2x-5y=-13-20
3x=-33
x=-33/3=-11....answer
multiplying equation 1 by 2 and adding equation 1&2
2x+10y-2x-(-5y)=-26-(-20)
10y+5y=-26+20
15y=-6
y=-6/15=-2/5......answer
