If Rebecca were three times as old as she was five years ago, she will be twenty-one more than two times her current age. How old is Rebecca?
\n" ); document.write( ":
\n" ); document.write( "Let x = her current age
\n" ); document.write( "then
\n" ); document.write( "(x-5) = her age 5 yrs ago
\n" ); document.write( ":
\n" ); document.write( "The equation:
\n" ); document.write( "3(x-5) = 2x + 21
\n" ); document.write( "3x - 15 = 2x + 21
\n" ); document.write( "3x - 2x = 21 + 15
\n" ); document.write( "x = 36 yrs old now
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the given statement:
\n" ); document.write( "3(36-5) = 2(36) + 21
\n" ); document.write( "3 * 31 = 72 + 21 \n" ); document.write( "
\n" );
