Let x = second side
\n" ); document.write( "Let 2x+8 = first side
\n" ); document.write( "Let 3x = third side\r
\n" ); document.write( "\n" ); document.write( "the perimeter is the addition of all three sides so:\r
\n" ); document.write( "\n" ); document.write( "x+2x+8+3x = 128
\n" ); document.write( "add the like terms:
\n" ); document.write( "6x+8 = 128
\n" ); document.write( "subtract 8 from both sides of the equation:
\n" ); document.write( "6x=120
\n" ); document.write( "divide both sides by 6 to get:
\n" ); document.write( "x=20\r
\n" ); document.write( "\n" ); document.write( "Hope you understand!
