Answer:
+ + + + += + + + + +
Step-by-step explanation:
DUH
I mean I think I'm right
substitute x for y-1
2(y-1)-y=6 distribute
2y-2-y=6 subtract y in 2y
y-2=6 add 2 to get y by itself
y=8
Put y back into equation x=y-1
x=8-1
X=7
The answer is C because when you rotate 90 degrees clockwise (x,y) becomes (y,-x)
The answer to your question is n is equal to 70
