Algebra.Com's Answer #2463 by Abbey(339)![]() ![]() ![]() You can put this solution on YOUR website! Split this into two parts:\r \n" ); document.write( "\n" ); document.write( "-1<3-2x and 3-2x<11 \n" ); document.write( "-1<3-2x: \n" ); document.write( "Subtract 2x from both sides of the equation: \n" ); document.write( "-4<-2x \n" ); document.write( "Divide by -2 (you have to switch the inequality sign when dividing by a negative number) \n" ); document.write( "2>x\r \n" ); document.write( "\n" ); document.write( "Second part: \n" ); document.write( "3-2x<11 \n" ); document.write( "subtract 3 from both sides: \n" ); document.write( "-2x<8 \n" ); document.write( "Divide by -2 (don't forget to switch the sign) \n" ); document.write( "x>-4\r \n" ); document.write( "\n" ); document.write( "Now we see that in order to have this be a true statement the value for x has to be greater than negative 4, but less than 2, so the solution set is: \n" ); document.write( "(-4,2)\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
