Hello,
\n" ); document.write( "We can set up 2 equations. Let c represent cranes and z will be zebras.
\n" ); document.write( "c+z=18
\n" ); document.write( "2c+4z=60
\n" ); document.write( "Multiply the first by -2 to get:
\n" ); document.write( "-2c-2z=-36
\n" ); document.write( "Add this to the second equation to get:
\n" ); document.write( "2z=24
\n" ); document.write( "Divide by 2 to get:
\n" ); document.write( "z=12
\n" ); document.write( "There we go. 12 zebras and 6 cranes.
\n" ); document.write( "Make sense?
