T = 4 + 2A
\n" ); document.write( "S = 5A - 8
\n" ); document.write( "T = S
\n" ); document.write( "Since T and S are equal, set them against each other
\n" ); document.write( "2A + 4 = 5A - 8
\n" ); document.write( "Subtract 2A from each side, and add 8 to each side
\n" ); document.write( "12 = 3A
\n" ); document.write( "Divide each side by 3
\n" ); document.write( "A = 4
\n" ); document.write( "If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
