Algebra.Com's Answer #211841 by unlockmath(1688) You can put this solution on YOUR website! Hello, \n" ); document.write( "We can set up 2 equations and solve it from there. Let \"x\" be adults and \"y\" represent children. \n" ); document.write( "x+y=400 \n" ); document.write( "6x+4.5y=2100 \n" ); document.write( "Multiply the first equation by -6 and add it to the second equation: \n" ); document.write( "-6x-6y=-2400 \n" ); document.write( "6x+4.5y=2100 \n" ); document.write( "This will give us: \n" ); document.write( "-1.5y=-300 Divide each side by -1.5 to get: \n" ); document.write( "y=200 children tickets. Now plug this into the first equation to find x: \n" ); document.write( "x=200 adult tickets \n" ); document.write( "Make sense? \n" ); document.write( "Get a book I wrote on the basics of math at: \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
