Let Angie's age be A and her mother's age be M\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Sum of angie and her mother is 64 years\r
\n" ); document.write( "\n" ); document.write( "A + M = 64 ------eq 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In 8 years angie will be (3/5) as old as her mother at that time. \r
\n" ); document.write( "\n" ); document.write( "(A + 8) = (3/5)(M + 8)\r
\n" ); document.write( "\n" ); document.write( "5(A + 8) = 3(M + 8 )
\n" ); document.write( "5A + 40 = 3M + 24
\n" ); document.write( "5A - 3M = 24 - 40
\n" ); document.write( "5A - 3M = -16 ------ eq 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiple eq1 by 3 and add with eq 2 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3A + 3M = 192
\n" ); document.write( "5A - 3M = -16
\n" ); document.write( "-------------------------------
\n" ); document.write( "8A = 176\r
\n" ); document.write( "\n" ); document.write( "A = 176/8 = 22\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute A = 22 in eq1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A + M = 64
\n" ); document.write( "22 + M = 64
\n" ); document.write( "M = 64 - 22
\n" ); document.write( "M = 42\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Angie's age is 22 and her mother's age is 42
\n" ); document.write( "
\n" );
