Let x be the length of each equal side and then 2x - 4 is the length of the base.
\n" ); document.write( "p = a + b + c
\n" ); document.write( "24 = a + b + c
\n" ); document.write( " $\"24+=+x+%2B+x+%2B+2x+-+4\"$
\n" ); document.write( "step 1 - combine like terms to get
\n" ); document.write( " $\"24+=+4x+-+4\"$
\n" ); document.write( "step 2 - add 4 to get
\n" ); document.write( " $\"28+=+4x\"$
\n" ); document.write( "step 3 - divide by 4 to get
\n" ); document.write( " $\"x+=+7\"$
\n" ); document.write( "the three sides are
\n" ); document.write( "{7, 7, 10} \n" ); document.write( "
