Answer:
option A
x = 4 1/3
Explanation:
7 1/2 - 5 3/4 / 3 1/2 + x divided by 1/2 + 1 1/4 / 1 1/5 + 3 1/2 = .6
15/2 - 23/4 / 7/2 + x divided by 1/2 + 5/4 / 6/5 + 7/2 = .6
(30 - 23)/ 4 / (7 + 2x) / 2 divided by (2 + 5) / 4 / (12 + 35) / 10 = .6
7/4 / (7 + 2x)/2 divided by 7/4 / 47/10 = .6
7/4 * 2/(7 + 2x) divided by 7/4 * 10/47 = .6
7/(14 + 4x) divided by 35/94 = .6
7/(14 + 4x) * 94/35 = .6
94/5(14 + 4x) = .6
94/(70 + 20x) = .6
94 = .6(70 + 20x)
94 = 42 + 12x
94 - 42 = 12x
52 = 12x
x = 52/12 = 26/6 = 13/3
thus, x = 4 1/3
