There are two more animals with 2 legs than animals with 4 legs. How many animals have 2 legs and how many have 4 legs. I know the answer is 9 animals with 2 legs and 7 animals with 4 legs but how do I write and equation to solve this. \n" ); document.write( "--------------- \n" ); document.write( "Quantity Equation:: t = f + 2 \n" ); document.write( "Legs Equation::::: 2t + 4f = 46 \n" ); document.write( "-------------------------------- \n" ); document.write( "Substitute for \"t\" and solve for \"f\": \n" ); document.write( "2(f+2) + 4f = 46 \n" ); document.write( "6f = 42 \n" ); document.write( "f = 7 (# of animals with 4 legs) \n" ); document.write( "----- \n" ); document.write( "Solve for \"t\": \n" ); document.write( "t = f+2 \n" ); document.write( "t = 9 (# of animas with 2 legs) \n" ); document.write( "================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "======== \n" ); document.write( " \n" ); document.write( " |
