M is midpont

AM = BM (definition of midpoint)

AB = AM + BM = 2*AM

7x + 9 = 2(4x)

7x + 9 = 8x

9 = x

MB = 4x = 4*9 = 36

or

MB = AB – AM

MB = (7x+9) – 4x = 3x+9

and then solve for x, same answer

2. I need a diagram. This is some form of four-sided figure or a triangle with a fourth point somewhere.
