Hello everyone!

I have this equation in two variables

y = A/x+b

I would like to find all the values for x and y that satisfy the equation.

I can't remember the correct procedure, can u help me?

Thanks!

I'm probably wrong in this but I suppose y = any real number and x= all real numbers excluding zero? since a fraction can never have a zero.

if the equation is as you posted it ...

$\displaystyle y = \frac{A}{x} + b$

... then first note that x cannot be 0.

substitute any other value of x and determine the corresponding value of y.

also, note that there are an infinite number of ordered pairs (x,y) that satisfy this equation.

to get specific solution(s), you'll need a second equation that relates x and y.
