L = larger number
\n" ); document.write( "S = smaller number
\n" ); document.write( "-----
\n" ); document.write( "L = 2*S + 11
\n" ); document.write( "L + S = 7 * S - 1
\n" ); document.write( "-----
\n" ); document.write( "substituting for L in the second equation by using the equality in the first equation, we get
\n" ); document.write( "(2*S + 11) + S = 7*S - 1
\n" ); document.write( "removing parentheses, we get
\n" ); document.write( "2*S + 11 + S = 7*S - 1
\n" ); document.write( "combining like terms, we get
\n" ); document.write( "3*S + 11 = 7*S - 1
\n" ); document.write( "subtracting 3*S from both sides of the equation, we get
\n" ); document.write( "11 = 7*S - 1 - 3*S
\n" ); document.write( "adding 1 to both sides of the equation, we get
\n" ); document.write( "11 + 1 = 7*S - 3*S
\n" ); document.write( "combining like terms, we get
\n" ); document.write( "12 = 4*S
\n" ); document.write( "dividing both side of equation by 4, we get
\n" ); document.write( "3 = S
\n" ); document.write( "which is the same as
\n" ); document.write( "S = 3
\n" ); document.write( "-----
\n" ); document.write( "substituting for S in the first equation, we get
\n" ); document.write( "first equation:
\n" ); document.write( "L = 2*S + 11
\n" ); document.write( "L = 2*3 + 11
\n" ); document.write( "L = 6 + 11
\n" ); document.write( "L = 17
\n" ); document.write( "-----
\n" ); document.write( "substituting for S and L in the second equation, we get
\n" ); document.write( "L + S = 7*S - 1
\n" ); document.write( "17 + 3 = 7*3 - 1
\n" ); document.write( "20 = 21 - 1
\n" ); document.write( "20 = 20
\n" ); document.write( "answer is correct
\n" ); document.write( "-----
\n" ); document.write( "answer is:
\n" ); document.write( "L = 17
\n" ); document.write( "S = 3
\n" ); document.write( "
\n" ); document.write( "
\n" );
