x+y= -1 Quantity A: x Quantity B: y 40 A) Quantity A is greater B) Quantity B is greater C) The two quantities are equal D) The relationship cannot be determined from the information given.
x+y= -1
make both variables the subject
x= -1-y and y=-1-x
when y=0 and when x=0
x=-1 y=-1
when y=1 and when x=1
x=-2 y=-2
If we keep on doing this, we will continue to have same value for both variables. Therefore, the question is not enough to show the relationship between bith quantities.
Answer: The relationship cannot be determined from the information given (D)
