document.write( "solving \"Linear system using substitution\"
\n" );
document.write( "4x-y=17  OR y = 4x-17 |Need to solve for one variable in either equation 
\n" );
document.write( "-9x+8y=2              |subsituting for y
\n" );
document.write( " -9x + 8(4x-17) = 2
\n" );
document.write( " -9x + 32x - 136 = 2
\n" );
document.write( "        23x = 138
\n" );
document.write( "          x = 6  and y = 7  (4*6 -17) Ordered pair Pt(6,7) is the solution
