Me what is the value of x? showing work would be appreciated - ! : )

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

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.
