Algebra.Com's Answer #476912 by josgarithmetic(39628) ![]() You can put this solution on YOUR website! Most important goal is form two simultaneous equations in two variables.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x = count of hats \n" ); document.write( "y = count of ties\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Account for the cost: \n" ); document.write( "This should immediately be simplified so it is easier to use in solving the system. Divide left and right by 5>.... \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Account for total quantity of items bought: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Solve this system in any way you want: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "------------------------- \n" ); document.write( "recommendation: multiply the \"15\" equation by 3, and then subtract from the \"50\" equation; and immediately find value for y.... \n" ); document.write( " |
