\"7 years ago I was 11 times older than my daughter, now I am 4 times older than her, how old am I?
\n" ); document.write( ".
\n" ); document.write( "Let x = your age
\n" ); document.write( "and d = your daughter's age
\n" ); document.write( "then
\n" ); document.write( "from \"7 years ago I was 11 times older than my daughter\"
\n" ); document.write( "x-7 = 11(d-7) (equation 1)
\n" ); document.write( ".
\n" ); document.write( "and from \"I am 4 times older than her\"
\n" ); document.write( "x = 4d (equation 2)
\n" ); document.write( ".
\n" ); document.write( "Solving equation 2 for d:
\n" ); document.write( "d = x/4
\n" ); document.write( ".
\n" ); document.write( "Substitute the above into equation 1:
\n" ); document.write( "x-7 = 11(d-7)
\n" ); document.write( "x-7 = 11(x/4-7)
\n" ); document.write( "Multiply both sides by 4:
\n" ); document.write( "4x-28 = 11(x-28)
\n" ); document.write( "4x-28 = 11x-308
\n" ); document.write( "-28 = 7x-308
\n" ); document.write( "280 = 7X
\n" ); document.write( "40 years old = x
\n" ); document.write( "
\n" ); document.write( "
\n" );
