Find an ordered pair that is a solution to the equation.

3x - y = 8

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

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
