You can put this solution on YOUR website!
Setup:
\n" ); document.write( "---------
\n" ); document.write( "Notice that each length is given in respect to the shotest piece.
\n" ); document.write( "Let A = the length of the shortest piece
\n" ); document.write( "Let B = the length of the second piece
\n" ); document.write( "Let C = the length of the third piece
\n" ); document.write( "Equation 1: \"B+=+A+%2B+2\"
\n" ); document.write( "Equation 2: \"C+=+2A+-+4\"
\n" ); document.write( "Equation 3: \"A+%2B+B+%2B+C+=+94\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solution:
\n" ); document.write( "---------------
\n" ); document.write( "Since we know what B and C equal in terms of A, we can substitute the values into equation 3
\n" ); document.write( "Equation 3: \"A+%2B+B+%2B+C+=+94\"
\n" ); document.write( "\"A+%2B+%28A+%2B+2%29+%2B+%282A+-+4%29+=+94\"
\n" ); document.write( "Combine like terms
\n" ); document.write( "\"4A+-+2+=+94\"
\n" ); document.write( "Add 2 to both sides
\n" ); document.write( "\"4A+=+96\"
\n" ); document.write( "Divide both sides by 4
\n" ); document.write( "\"highlight%28A+=+24%29\"\r
\n" ); document.write( "\n" ); document.write( "Now we can find the other lengths by replacing A with 24 in equations 1 & 2
\n" ); document.write( "Equation 1: \"B+=+A+%2B+2\"
\n" ); document.write( "\"B+=+24+%2B+2\"
\n" ); document.write( "\"highlight%28B+=+26%29\"
\n" ); document.write( "Equation 2: \"C+=+2A+-+4\"
\n" ); document.write( "\"C+=+2%2A%2824%29+-+4\"
\n" ); document.write( "\"highlight%28C+=+44%29\"\r
\n" ); document.write( "\n" ); document.write( "Check the answers:
\n" ); document.write( "------------------
\n" ); document.write( "We can check the answers by placing them back into eqaution 3
\n" ); document.write( "Equation 3: \"A+%2B+B+%2B+C+=+94\"
\n" ); document.write( "\"24+%2B+26+%2B+44+=+94\"
\n" ); document.write( "\"highlight%2894+=+94%29\"
