GIVEN: ---: 3x-4y=17
\n" ); document.write( " ---: y=x-5\r
\n" ); document.write( "\n" ); document.write( " substitute Y into x-5
\n" ); document.write( "---: 3x-4(4x-5)=17
\n" ); document.write( "---: 3x-4x+20=17
\n" ); document.write( "---: -x=17-20
\n" ); document.write( "---: -x=-3
\n" ); document.write( "multiply both side with -1
\n" ); document.write( "---: -1(-x=-3)-1
\n" ); document.write( "---: x=3 (ANSWER)
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "then use the second given to find the answer for the Y
\n" ); document.write( ".
\n" ); document.write( "y=3-5
\n" ); document.write( "y=-2 (ANSWER)
\n" ); document.write( "
\n" );
