Solve the system, using substitution. Write the solution as an ordered pair. x = 2y - 2 and 3x - y = 14 (6, 4) (4, 6) (1, 0) (0, 1) no solution

    Substitute your x = 2y-2 for x in the second equation. and solve for y.

    Once you have your y, plug in that value back for the first equation to get your x.

    3(2y - 2) - y = 14 5y-6 = 14 y=4 => x=6 (6,4)

    5y = 14+6 5y = 20 y=4 them from 3x - y = 14 3x - (4) = 14 3x = 18 x=6 so (6,4)
