Find an ordered pair that is a solution to the equation.<br><br> 3x - y = 8
mojhsa [17]

Answer:

Step-by-step explanation:

There are so many order pairs that can solve this equation.

To solve this problem, we choose any value of x and find y;

  Given expression;

            3x  - y  = 8

 if x  = 0,

           3(0) - y  = 8

                 -y  = 8

                 y = -8;

  (0,-8) is a solution

ii.

  if x  = 1,

          3(1) - y = 8

               - y = 8 - 3

                  y = -5

        (1, -5) is a solution
