Since they're both equal to y set them equal to each other and solve for x.
\n" ); document.write( "\"9x%2B9=4x-9\"
\n" ); document.write( "\"5x=-18%7D%7D%0D%0A%7B%7B%7Bx=-18%2F5\"
\n" ); document.write( "Then use either equation to solve for \"y\"
\n" ); document.write( "\"y=9%28-18%2F5%29%2B45%2F5\"
\n" ); document.write( "\"y=-162%2F5%2B45%2F5\"
\n" ); document.write( "\"y=-117%2F5\"
\n" ); document.write( "
