A + B = 99
\n" ); document.write( "A - 2B = 15
\n" ); document.write( "Use the second equation and add 2B to each side to get:
\n" ); document.write( "A = 2B + 15
\n" ); document.write( "Now substitute the value of A from that equation into the first equation:
\n" ); document.write( "A + B = 99
\n" ); document.write( "(2B + 15) + B = 99
\n" ); document.write( "Add
\n" ); document.write( "3B + 15 = 99
\n" ); document.write( "Subtract 15 from each side
\n" ); document.write( "3B = 84
\n" ); document.write( "Divide each side by 3
\n" ); document.write( "B = 28
\n" ); document.write( "If B is 28, then A is 99-28, or 71
\n" ); document.write( "
\n" ); document.write( "
\n" );
