A system of equations is shown. 3x+4y=30 3x+5y=33. What is the value of y in the solution to the system of equations

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
