Algebra.Com's Answer #24514 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! From -8 - 3(X - 4) < 3(6 - X) \n" ); document.write( "let us multiply everything out first and get \n" ); document.write( "-8 - 3x + 12 < 18 - 3x \n" ); document.write( "now combine \n" ); document.write( "4 - 3x < 18 - 3x \n" ); document.write( "Now add 3x to both sides and get \n" ); document.write( "4 < 18 \n" ); document.write( "Now ask yourself, \"For what values of x is 4 less than 18?\" \n" ); document.write( "Well, all of them. That's why the answer in interval notation is \n" ); document.write( "(-oo, oo) . \n" ); document.write( " |
