Let F = fame and E = EJ. \n" ); document.write( "Read each sentence and translate into math. \n" ); document.write( "Fame is 10 years older than EJ. \n" ); document.write( "This translates to: \n" ); document.write( "(i) F = E + 10. \n" ); document.write( "Five years ago, EJ was two years more than one-fourth as old as Fame. \n" ); document.write( "Here you have to reduce both people by 5, -5. \n" ); document.write( "(ii) E - 5 = (1/4)(F - 5) + 2. \n" ); document.write( "We can use substitution of (i) into (ii) \n" ); document.write( "(iii) E - 5 = (1/4)(E + 10 - 5) + 2 \n" ); document.write( "Solve for E. \n" ); document.write( "E - 5 = .25E + 2.5 -1.25 + 2 \n" ); document.write( ".75E = 8.25 \n" ); document.write( "E = 11 \n" ); document.write( "F = 21. \n" ); document.write( " \n" ); document.write( " |
