You can put this solution on YOUR website!
There are several methods for solving this system of equations. I will use the method of addition:
\n" ); document.write( "First, line-up the variables:
\n" ); document.write( "-x+3y=5
\n" ); document.write( "3x-9y=-10\r
\n" ); document.write( "\n" ); document.write( ".
\n" ); document.write( ".Next, multiply one of the equations by a number that will cause a variable to cancel out:
\n" ); document.write( "3(-x+3y=5)=-3x+9y=15
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Add the equations together:
\n" ); document.write( "-3x+9y=15
\n" ); document.write( "3x-9y=-10
\n" ); document.write( "___________
\n" ); document.write( "0=-5 (incorrect answer, therefore, there is \"no solution\"]
\n" ); document.write( "
\n" );
