Question

.69x + .99y = 25.00 (roughly)
What is x, y?

Answer 1

x and y could have many values.

Answer 2

You have 2 unknowns so you need 2 equations

Answer 3

How do I set up two equations when this is all the information I have received?

Answer 4

Think of your equation as a line y = -0.7x +25 (roughly)

Your x,y pairs are anywhere on that line

Answer 5

So, for example, if x is 0, y is 25 but any pairs that are on the line will do.

You cannot specify x,y any more than that without further information.

Answer 6

thank you. Perhaps it's a trick question. I appreciate your help.
