ANSWER::
\n" ); document.write( "Let Lucy's age be X and Amy's age must now be 2X (Due to the fact that it is said Amy is twice as old as Lucy)
\n" ); document.write( "The current age of Amy is 2X and for Lucy is X
\n" ); document.write( "Then, Three yrs to come we have (2x+3->Age for Amy and X+3->age for Lucy)
\n" ); document.write( "Also the sum of their age will be 42:-> (2X+3)+ (X+3)=42
\n" ); document.write( "open the brackets to have 3X+6=42, solve for X now as You will get X= 12
\n" ); document.write( "THEREFORE, Amy's age is 2X= 2*12= 24 years
\n" ); document.write( "
\n" );
