How many liters of water should be evaporated from 60 liters of a 28% salt solution so that the remaining solution contains 32% salt? a. 7.5 liters b. 8.4 liters c. 43.2 liters d. 52.5 liters

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
