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

3x + 24y = 24
27x  15y = 15
Divide both sides of the first equation by 3.
x + 8y = 8
Transpose 8y.
x = 8  8y
Substitute 88y 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.
