document.write( "I was asked to find the solution by writing and solving a system of 2 linear equations.\r
\n" );
document.write( "\n" );
document.write( "so far i have that: k= number of cats and c= number of canaries\r

document.write( "1st Value Equation: 10k + 15c = 360

document.write( "2nd Value Equation: 10(k-2) + 15(c/2) = 220

document.write( "Rewrite for elimination:
