The Set Up:
\n" ); document.write( "Let A = # of 5 peso bills
\n" ); document.write( "Let B = # of 10 peso bills.
\n" ); document.write( "Equation 1: \"A+%2B+B+=+29\"
\n" ); document.write( "Equation 2: \"5A+%2B+10B+=+225\"
\n" ); document.write( "------------------------
\n" ); document.write( "Solution:
\n" ); document.write( "Solve equation 1 for one of the variables.
\n" ); document.write( "Equation 1: \"A+%2B+B+=+29\"
\n" ); document.write( "\"A+=+29+-+B\"
\n" ); document.write( "Now plug (29 - B) into equation 2 for A
\n" ); document.write( "Equation 2: \"5A+%2B+10B+=+225\"
\n" ); document.write( "\"5%2A%2829+-+B%29+%2B+10B+=+225\"
\n" ); document.write( "Simplify
\n" ); document.write( "\"145+-+5B+%2B+10B+=+225\"
\n" ); document.write( "Combine like terms
\n" ); document.write( "\"145+%2B+5B+=+225\"
\n" ); document.write( "Subtract 145 from both sides
\n" ); document.write( "\"5B+=+80\"
\n" ); document.write( "Divide both sides by 5
\n" ); document.write( "\"highlight%28B+=+16%29\"
\n" ); document.write( "Now solve plug 16 into equation 1 for B and solve for A
\n" ); document.write( "\"A+=+29+-+B\"
\n" ); document.write( "\"A+=+29+-+%2816%29\"
\n" ); document.write( "\"highlight_green%28A+=+13%29\"
\n" ); document.write( "
\n" );
