Solve and check each equation.
14. 3 x + 5 + 2 = 7

15. x +1 = 3x + 7
3x + 4 = 1+ x +1
17. The velocity of a free falling object is given by V = 2gh , where V is velocity (in meters per second), g is
acceleration due to gravity (in meters per second squared), and h is the distance (in meters) the object has
fallen. The value of g depends on which body/planet is attracting the object. If an object hits the surface with
a velocity of 30 meters per second, from what height was it dropped on Earth where g = 9.81 m/s2?
