B = A - 12
\n" ); document.write( "4A = 3B + 90
\n" ); document.write( "Substitute the value of B from the first equation into the second
\n" ); document.write( "4A = 3B = 90
\n" ); document.write( "4A = 3(A-12) +90
\n" ); document.write( "4A = 3A - 36 + 90
\n" ); document.write( "4A = 3A + 54
\n" ); document.write( "A = 54
\n" ); document.write( "If the larger number is 54, then the smaller number is 42.
Check:
\n" ); document.write( "Four times the larger (4*54=216) exceeds 3 times the smaller (3*42=126) by 90 (126+90=216)
\n" ); document.write( "
\n" );
