Find the point of intersection of the lines 3=6x-y and 3x-2y=24 ?

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.

If f(x)=x+7 and g(x)=1/x what is (fog)(x)

One positive integer is 2 less than another. the product of the two integers is 24. what are the integers
