If there are 500 mg of medicine in 5 ml of liquid, we need to set up a proportion to find out how much liquid medication has 125 mg of medicine in it. Set up the proportion as follows:
.
Cross multiply to get 500x = 625. Divide by 500 to get that you need 1.25 ml of liquid if your dose is 125 mg of medicine.
Multiply both sdies by 10 to get rid of the fractions
20(4x+3)/5-60(x-2)/2=5
4(4x+3)-30(x-2)=5
distribute
16x+12-30x+60=5
add like terms
-14x+72=5
subtract 72 from both sdies
-14x=-67
multiplyh -1
14x=67
divide both sdies by 14
x=67/14
