Algebra.Com's Answer #437288 by tutor_paul(519)![]() ![]() You can put this solution on YOUR website! The key to this problem is translating the words into equations. Let's take it one phrase at a time. \"agnes is three times as old and joseph.\" \n" ); document.write( "Let A=Agnes' Age \n" ); document.write( "Let J=Joseph's Age \n" ); document.write( "You can represent the above words as: \n" ); document.write( " \n" ); document.write( "Now let's take the second phrase: \"their combined ages is 64.\" \n" ); document.write( "You can represent these words as: \n" ); document.write( " \n" ); document.write( "---------------- \n" ); document.write( "Now you have 2 equations and 2 unknown variables. Anytime you have as many equations as unknowns, you can solve the problem! \n" ); document.write( "To do so, Substitute the expression for A in the first equation above into the second equation: \n" ); document.write( " \n" ); document.write( "Solve for J: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "To find A, substitute the value for J into the first equation, and solve for A. I will leave that part to you. \n" ); document.write( "=================== \n" ); document.write( "Good Luck, \n" ); document.write( "tutor_paul@yahoo.com \n" ); document.write( " \n" ); document.write( " |
