1.8 = (5-x)/100 * 150/x

= 150/100 * (5-x)/x

= 3/2 (5/x - 1)

9/5 = 15/2x - 3/2

9/5 + 3/2 = 15/2x

33/10 = 15/2x

10/33 = 2x/15

10/33 * 15/2 = x

x = 150/66 = 25/11

1.8=[(5.0-x)/100]/(x/150)

1.8 =[(5.0-x)/100]*150/x

1.8=(5.0-x)150/100* x

1.8 =[(5*150)-(x*150)]/100x

1.8= 750-150x/100x

1.8*100x=750-150x

180x=750-150x

180x+150x=750

330x=750

divide through by330

330x/330=750/330

x=2.27
