what is the ordered pair for x-2y=3

Question

i need to know the ordered pair for this question

Answer 1

Remember that an ordered pair (x,y) represents those values of x and y that make the equation true:

 

To find one ordered pair (there are many since this is a linear equation) that solves this expression, pick a value of one of the variables and then solve for the other...e.g.,

 

Suppose x = 0.

 

Then:

 

0 - 2y = 3

 

-2y = 3

 

Divide both sides by -2:

 

(-2y)/-2 = 3/-2

 

y = -(3/2)

 

The ordered pair is (0, -(3/2))

 

If you pick a different x, then you'll get a different y.
