The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

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.

Solve the equation. 2x - 8(x+1)= 6(2x - 3)
