Solve using the substitution method. Sh 3x + 24y = 24, 27x – 15y = -15 .

  • math - ,

    3x + 24y = 24

    27x - 15y = -15

    Divide both sides of the first equation by 3.

    x + 8y = 8

    Transpose 8y.

    x = 8 - 8y

    Substitute 8-8y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
