y+9=3x-2y+6
\n" ); document.write( "y + 2y = 3x + 6 -9
\n" ); document.write( "3y = 3x - 3
\n" ); document.write( "y = x -1 .... equation 1 \r
\n" ); document.write( "\n" ); document.write( "5-3x+5y=-2x+4y+3\r
\n" ); document.write( "\n" ); document.write( "5y - 4y = 2x + 3x - 5 + 3
\n" ); document.write( "y = 5x - 2 ... equation 2 \r
\n" ); document.write( "\n" ); document.write( "Equation 1 = Equation 2 \r
\n" ); document.write( "\n" ); document.write( "x - 1 = 5x - 2 \r
\n" ); document.write( "\n" ); document.write( "2 - 1 = 5x - x
\n" ); document.write( "1 = 4x
\n" ); document.write( "x = 1/4 \r
\n" ); document.write( "\n" ); document.write( "when x = 1/4 ; $\"y=%281%2F4%29-1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y+=+-+3%2F4\"$ \r
\n" ); document.write( "\n" ); document.write( "Answer: x = 1/4 and y = -3/4 \n" ); document.write( "

\n" );
