document.write( "y = 2x+3 green  p(0,3) and P(3,9) Plot, connect with line
\n" );
document.write( "y = 3x-6 blue   P(0, -6) and P(2, 0) Plot, connect with line
\n" );
document.write( "Line intersect at(9,21), x = 9,  y = 21 the solution
\n" );

document.write( "Let's see
\n" );
document.write( "15x - 5y = 30
\n" );
document.write( " 2x - y = -3  Multiply by 5 and subtracting from 1st EQ to eliminate y
\n" );
document.write( "     5x = 45

document.write( "      x = 9  and using y = 2x+3,  y = 21\r
