You can put this solution on YOUR website!
since the lengths of the sides of the triangle are all equal, then you get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x+7 = 3x+4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for x as follows:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "start with 2x+7 = 3x+4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtract 2x from both sides of the equation and subtract 4 from both sides of the equation to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7-4 = 3x-2x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "simplify to get 3 = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the value of x is equal to 3.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "each side of the triangle will be equal to 2x+7 = 6+7 = 13.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you could have used the other formula as well because 3x+4 = 9+4 = 13.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since all the sides are equal, the third side is also equal to 13.
\n" ); document.write( "
\n" ); document.write( "
\n" );
