3x-8y=10
\n" ); document.write( "x-4y=3
\n" ); document.write( "I'll use the substitution method to solve;
\n" ); document.write( "x=3+4y
\n" ); document.write( "Substitute 3+4y for x;
\n" ); document.write( "3(3+4y)-8y=10
\n" ); document.write( "9+12y-8y=10
\n" ); document.write( "12y-8y=10-9
\n" ); document.write( "4y=1
\n" ); document.write( "y= $\"1%2F4\"$
\n" ); document.write( "Now substitute $\"1%2F4\"$ for y;
\n" ); document.write( "x-4 $\"%281%2F4%29\"$ =3
\n" ); document.write( "x-1=3
\n" ); document.write( "x=4
\n" ); document.write( "So the answer;
\n" ); document.write( "y= $\"1%2F4\"$
\n" ); document.write( "x=4
\n" ); document.write( "=) \n" ); document.write( "

\n" );
