\n" );
document.write( "*Note: to solve for x, we need to isolate x on one side of the equal sign
\n" );
document.write( "also note,for ex : (-1)*(-2) = +2  and 1*(-2) = -2 for ex
\n" );
document.write( "-4x = 20-(-4)
\n" );
document.write( "-4x = 20 + (-1)(-4)
\n" );
document.write( "-4x = 20 + 4
\n" );
document.write( "-4x = 24
\n" );
document.write( "dividing both sides of the equation by -4
\n" );
document.write( "-4x/-4 = 24/-4 
\n" );
document.write( "x = -6 \n" );
