Algebra.Com's Answer #86363 by checkley71(8403)![]() ![]() ![]() You can put this solution on YOUR website! AN INEQUALITY (> OR <) IS SIMILIAR TO AN EQUATION WITH ONE MAJOR DIFFERENCE WHICH I'LL COVER WHEN WE GET TO IT. \n" ); document.write( "-3X-5>X+15 \n" ); document.write( "-3X-X>15+5 HERE WE SUBTRACT X +5 FROM EACH SIDE. \n" ); document.write( "-4X>20 HERE WE COMBINE LIKE TERMS. NOW WE GET TO THE MAJOR DIFFERENCE BETWEEN (>,<)& = SIGNS. \n" ); document.write( "WHENEVER YOU DIVIDE OR MULTIPLY BOTH SIDES BY A NEGATIVE THE > SIGN CHANGES TO A < SIGN & VISE-VERSA. \n" ); document.write( "X<20/-4 \n" ); document.write( "X<-5 IS THE ANSWER. \n" ); document.write( "PROOF \n" ); document.write( "LET X=-5.1 \n" ); document.write( "-3(-5.1)-5>5.1+15 \n" ); document.write( "15.3-5>20.1 \n" ); document.write( "20.3>20.1 \n" ); document.write( " |
