Answer:
AU AB
------ = ---------
AV AC
20x + 108 20X + 381
--------- = ---------------
372 589
(20x + 108)* 589 = (20X + 381)*372
11780 X + 63612 = 7440X + 141732
4340 X - 78120 = 0
4340 X = 78120
X = 78120/4340 = 18
CHECK:
AU = 20*18 + 108 = 360 + 108 = 468
AB = 741
468/372 = 741/589 are equal ratios
