Algebra.Com's Answer #156173 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! using the two EQUAL sides ___ 4x - 3 = 2x + 1 ___ 2x = 4 ___ x = 2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "4x - 3 = 4(2) - 3 = 5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2x + 1 = 2(2) + 1 = 5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "3x = 3(2) = 6\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so the sides are 5, 5, and 6 \n" ); document.write( " |
