Question 766061
x = volume of 30% acid to use.
y = volume of 65% acid to use.


{{{(65*y+30*x)/525=50}}} and {{{x+y=525}}}


Simplify the rational equation by division of both sides by 5.
{{{(13y+6x)/525=10}}} and multiply them by 525.
{{{13y+6x=5250.}}}
{{{6x+13y=5250}}}


Solve the system:
{{{highlight(6x+13y=5250)}}}
{{{highlight(x+y=525)}}}
