SOLUTION: Explain how you find ordered-pair solutions of the equation 3x - 5y= 15. then find two solutions.

First, I solve the equation for y: y = ,  or,  which is the same, y = .


Then I assign any (arbitrary) value for x. For example, let x = 0.


Next, I calculate the corresponding value of y: y =  = -3.

It gives the first ordered-pair solution: (x,y) = (0,-5).



Now, let x = 5 is next arbitrary number. Then

y =  = 0.


Thus the pair (x,y) = (5,0) is the second ordered-pair solution.


In this way, you can create INFINITELY MANY ordered-pair solutions.
