You can put this solution on YOUR website!
Write a system of linear equations in two variables having $\"%22%28x%2Cy%29%22=%22%28-2%2C7%29%22\"$ as a solution set. (More than one system is possible.) Make sure that your system has two equations with two variables!

document.write( "Make up any 2 numbers for the coefficients of x and y for the first\r\n" );
document.write( "equation, say  and , so write \r\n" );
document.write( "\r\n" );

document.write( "equation, say  and , so write \r\n" );

document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So the second equation will be  \r\n" );
