You can put this solution on YOUR website!
multipy -1 to the equation x-3y=4
\n" ); document.write( "your equation will be
\n" ); document.write( "-x+3y=-4
\n" ); document.write( "then elimate -x with x
\n" ); document.write( "-x+3y=-4
\n" ); document.write( " x+5y=-4
\n" ); document.write( "-x and x is now elimated, so the equation will be
\n" ); document.write( "8y=-8, the divide both sides by 8
\n" ); document.write( "8y/8=-8/8
\n" ); document.write( "then y=-1
\n" ); document.write( "plug in -1 to the previous equation
\n" ); document.write( "x-3(-1)=4
\n" ); document.write( "x+3=4, the subtract 3 form both sides of the equation
\n" ); document.write( " -3 -3
\n" ); document.write( "the x=1, so your solution is (1,-1)
\n" ); document.write( "
\n" );
