b
Step-by-step explanation:
I had the same question
X+y=-1
3x-y=21
add them equations
x+y=-1
<u>3x-y=21 +</u>
4x+0y=20
4x=20
divide by 4
x=5
x+y=-1
5+y=-1
minus 5 both sides
y=-6
(x,y)
(5,-6)
D is answer

<h3>THE MID TERM SPLITTING OF THE EQUATION IS :</h3>





now shifted to 5 units left
therefore,
x=-4
hope it helps you mate thanks for the question and if possible please mark it as brainliest
