Explanation & Answer
Thank you for the opportunity to help you with your question! Hope your day is going well!
Our problem:
x+y=-1
x+4y=-4
Step 1: First look to see if the x's or y's have the same coefficient...The x's do, so all we have to do is simply subtract both equations from each other
x+y=-1
-x-4y=4
-3y=3
y=-1
Step 2: Solve for x
x+y=-1
x+(-1)=-1
x-1=-1
x=0
Step 3: Check your work
Notice that 0+-1=-1 check!
also 0+4(-1)=-4 Check!
Our order pair is (0,-1).
