Algebra.Com's Answer #698870 by math_helper(2461)![]() ![]() You can put this solution on YOUR website! It will never happen. Rajesh is younger than Reeta. \n" ); document.write( "=============== \n" ); document.write( "If you meant 'Rajesh is now 20 years old and reeta is 4 years older than him.In how many years Rajesh be twice as old as Reeta IS NOW?' Then the answer is 28 years b/c you're looking for when Rajesh is 48 years old (2x Reeta's CURRENT age). \r \n" ); document.write( "\n" ); document.write( "Rajesh's age = 20 \n" ); document.write( "Reeta's age = 20+4 = 24 \n" ); document.write( "x = number of years until Rajesh is twice Reeta's current age\r \n" ); document.write( "\n" ); document.write( " 20+x = 2(24) <<< this is the formulation, or equation that needs solving \n" ); document.write( " 20+x = 48 \n" ); document.write( " x = 48 - 20 \n" ); document.write( " x = 28 <<< answer is found by solving the original equation for x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
