HI!!

misty1212 · Answer

guess we need a variable here right?  lets call $x$ the number of liters of 20% solution

Hai!

misty1212 · Answer

then the amount of acid will be 
$$.08\times 12+.2\times x$$ and the total amount is $12+x$ which is $16\%$ acid so 
$$.08\times 12+.2\times x=.16\times (12+x)$$ and you can solve this for $x$
