Question 1151458
Let {{{ x }}} = liters of water to be added
{{{ .08*6 = .48 }}} = liters of boric acid in the 8% solution
------------------------
{{{ .48 / ( 6 + x ) = .05 }}}
{{{ .48 = .3 + .05x }}}
{{{ .05x = .18 }}}
{{{ x = 3.6 }}}
3.6 liters of water should be added
-----------------------------------------
check:
{{{ .48 / ( 6 + x ) = .05 }}}
{{{ .48 / ( 6 + 3.6 ) = .05 }}}
{{{ .48 / 9.6 = .05 }}}
{{{ .05 = .05 }}}
OK
