Algebra.Com's Answer #161686 by tutor_paul(519)![]() ![]() You can put this solution on YOUR website! Let V be the cost of a VHS tape \n" ); document.write( "Let C be the cost of a Cassette tape \n" ); document.write( "--------------------------- \n" ); document.write( "From the information given you can write the following equations: \n" ); document.write( "Equation #1: \n" ); document.write( "Equation #2: \n" ); document.write( "You have 2 equations with 2 unknowns. That means you can solve the problem. \n" ); document.write( "---------------------------- \n" ); document.write( "Solve Equation #1 for V in terms of C: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "---------------------------- \n" ); document.write( "Substitute this expression for V into Equation #2 and Solve for C: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "---------------------------- \n" ); document.write( "Substitute this value for C back into Equation #2 and solve for V: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "============================ \n" ); document.write( "To check your answers, plug these values of C and V back into Equations #1 and #2 and make sure the equations hold true. \n" ); document.write( "============================ \n" ); document.write( "Good Luck, \n" ); document.write( "tutor_paul@yahoo.com\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
