Question 348538
Let {{{A}}} be the amount of 40% solution.
Let {{{B}}} be the amount of 60% solution.
Volume eqaution:
1.{{{A+B=8}}}
Concentration equation:
{{{40A+60B=55(8)}}}
2.{{{2A+3B=22}}}
Multiply eq. 1 by 2 and subtract it from eq. 2,
{{{2A+3B-2A-2B=22-16}}}
{{{highlight(B=6)}}}liters
Then from eq. 1,
{{{A+6=8}}}
{{{highlight(A=2)}}}liters
