Anna made the following announcement:
\n" ); document.write( "In 7 years, I will be half my mother's age. Thirteen years ago, she was 6 times as old as i was then.
\n" ); document.write( "How old is Anna now?
\n" ); document.write( "--------------------------------------
\n" ); document.write( "Let anna be x yrs old now.
\n" ); document.write( "Let mother be y yrs old now.
\n" ); document.write( "--------------------------------
\n" ); document.write( "EQUATIONS:
\n" ); document.write( "x+7 = (1/2)(y+7)
\n" ); document.write( "Y-13 = 6(x-13)
\n" ); document.write( "-------------------
\n" ); document.write( "Rearrange to solve:
\n" ); document.write( "2x - y = -7
\n" ); document.write( "6x -y = -7*-13
\n" ); document.write( "---------------------
\n" ); document.write( "Subtract 1st equation from 2nd to get:
\n" ); document.write( "4x = -7*-14
\n" ); document.write( "x= 24.5 yrs old now (Anna's age now)
\n" ); document.write( "=================
