Algebra.Com's Answer #545636 by suzanna18(1)![]() ![]() ![]() You can put this solution on YOUR website! The second side would be x \n" ); document.write( "So the first side would be 2×x \n" ); document.write( "And the third is 3×x-1 \n" ); document.write( "So the perimeter is 17= x + 2×x + 3×x-1 \n" ); document.write( "16= 6×x \n" ); document.write( "16/6= 6×x/6 \n" ); document.write( "x= 8/3 \n" ); document.write( "2×x= 16/3 \n" ); document.write( "3×x-1=7 \n" ); document.write( " |
