let a = no. done by Angela
\n" ); document.write( "let p = no. done be Paula
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "Angela did 5 fewer than twice as many sit-ups as Paula.
\n" ); document.write( "a = 2p - 5
\n" ); document.write( ":
\n" ); document.write( " Between the two of them, they did a total of 136 sit-ups.
\n" ); document.write( "a + p = 136
\n" ); document.write( "Replace a with (2p-5) in the above equation, find p
\n" ); document.write( "(2p - 5) + p = 136
\n" ); document.write( "2p + p = 136 + 5
\n" ); document.write( "3p = 141
\n" ); document.write( "p + $\"141%2F3\"$
\n" ); document.write( "p = 47 pull-ups by Paula
\n" ); document.write( "then
\n" ); document.write( "a = 2(47) - 5
\n" ); document.write( "a = 94-5
\n" ); document.write( "a = 89 pull-ups by Angela
\n" ); document.write( ";
\n" ); document.write( ";
\n" ); document.write( "Check that in the statement:
\n" ); document.write( "they did a total of 136 sit-ups.
\n" ); document.write( "47 + 89 = 136 \n" ); document.write( "

\n" );
