You can put this solution on YOUR website!
x, y, z, count of child tickets, adult tickets, senior tickets.\r
\n" ); document.write( "\n" ); document.write( "x=3+y, and y-1=z.
\n" ); document.write( "Accounting for cost, 10x+15y+13z=131.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You could solve the two first equations for y, and equate those expressions, and use one of them to substitute for y in the cost equation. You then have any two equations in x and z. \r
