You can put this solution on YOUR website!
Since you have 2 variables x and y in the given equation, you would require one more equation to obtain values of x and y.
\n" ); document.write( "

\n" ); document.write( "6x + 9y = 15
\n" ); document.write( "3[2x + 3y = 5]
\n" ); document.write( "

\n" ); document.write( "2x + 3y = 5
\n" ); document.write( "

\n" ); document.write( "then,
\n" ); document.write( "x=(5-3y)/2
\n" ); document.write( "y=(5-2x)/3
\n" ); document.write( "

\n" ); document.write( "Substitute either of these two relative values of x or y in the 2nd equation.
\n" ); document.write( "Then you will have an equation entirely in x or y.
\n" ); document.write( "solve to obtain the required value,and then use the relative value to obtain the second variable.
\n" ); document.write( "
