Let x = capacity of container (in gallons)

jim_thompson5910 · Answer

it's currently 1/2 full, so we have (1/2)*x gallons of water in it right now

jim_thompson5910 · Answer

you pour in 3 more gallons, so you add 3 to (1/2)*x to get (1/2)*x+3

the current gallon amount is now at (1/2)*x+3

jim_thompson5910 · Answer

at this amount, the container is 7/10 full, so (1/2)*x+3 is equal to (7/10)*x

jim_thompson5910 · Answer

the equation you need to solve is 

(1/2)*x+3 = (7/10)*x

I'll let you do this
