Which ordered pair is a solution of the equation y equals x minus 3
Rom4ik [11]
Y = x-3

Basically you just need to plug in an x value and solve for y
y = x - 3
y = (4) - 3
y = 1

In this case, the ordered pair of this equation would be (4, 1)

You can do this given any x or y coordinate

1/3(33x +15) - 1/3 ( 21x +18) =10
inn [45]
          ¹/₃(33x + 15) - ¹/₃(21x + 18) = 10
¹/₃(33x) + ¹/₃(15) - ¹/₃(21x) - ¹/₃(18) = 10
                             11x + 5 - 7x - 6 = 10
                             11x - 7x + 5 - 6 = 10
                                            4x - 1 = 10
                                                + 1   + 1
                                                 4x = 11
                                                  4      4
