Algebra.Com's Answer #54044 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let E be Edmund's age and F be Frank's age. \n" ); document.write( "From the problem description, you can write: \n" ); document.write( "1) E = F+3 and \n" ); document.write( "2) E+F = 19 \n" ); document.write( "Now, you substitute the E from equation 1) into equation 2) and solve for F. \n" ); document.write( "2a) (F+3) + F = 19 Simplify. \n" ); document.write( "2F+3 = 19 Subtract 3 from both sides. \n" ); document.write( "2F = 16 Divide both sides by 2. \n" ); document.write( "F = 8 This is Frank's age. \n" ); document.write( "E = F+3 \n" ); document.write( "E = 8+3 \n" ); document.write( "E = 11 This is Edmund's age. \n" ); document.write( " |
