How to solve a simultaneous equation involved with fractions?

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.

Consider the following function. which of the following graphs corresponds to the given function? w. x. y. z. a. z b. y c. x d.
