Answer:
y = 5
Step-by-step explanation:
−x+y=0 −2x+y=−5
Multiply the first equation by -2
-2(-x+y=0)
2x-2y =0
Add this to the second equation
2x-2y =0
−2x+y=−5
-------------------
0x -y = -5
-y =-5
Multiply by -1
y = 5
Answer:
what are the options? I would say something like 50-60
A = LW
A = 188
W = 4
188 = 4L
188/4 = L
47 = L....so the length is 47 meters
