Algebra.Com's Answer #37464 by venugopalramana(3286) You can put this solution on YOUR website! SEE THE FOLLOWING EXAMPLE AND TRY...IF STILL IN DIFFICULTY PLEASE COME BACK. \n" ); document.write( "------------------------------------------------------------------ \n" ); document.write( "I really don't understand this problem. Can you please help me? \n" ); document.write( "3(1-3x)+2=4x+14........OK \n" ); document.write( "3-9x+2=4x+14................GOOD \n" ); document.write( "so then add or subtract from both sides? \n" ); document.write( "3-9x+9x+2=13+14......HERE YOU GOT CONFUSED..THE STEPS INVOLVED ARE \n" ); document.write( "1.REMOVE BRACKETS ......THIS YOU HAVE DONE. \n" ); document.write( "2.TRANSFER ALL UNKNOWN TERMS TO ONE SIDE.... USUALLY L.H.S. AND KNOWN TERMS TO ONE SIDE ...USUALLY R.H.S. \n" ); document.write( "3.THIS TRANSFER YOU CAN THINK OF AND DO AS FOLLOWS.... \n" ); document.write( "EVERY TERM HAS A + OR - SIGN INFRONT OF IT.WHEN YOU TRANSFER THAT TERM FROM ONE SIDE TO ANOTHER ,+ BECOMES - AND - BECOMES PLUS. \n" ); document.write( "THIS IS BECAUSE...AS YOU WERE TRYING TO SAY 'ADD OR SUBTRACT FROM BOTH SIDES' \n" ); document.write( "AN EQUATION IS UNALTERED IF WE ADD OR SUBTRACT SAME QUANTITY FROM BOTH SIDES OF THE EQN.SO IF WE WANT TO REMOVE +4X ABOVE FROM R.H.S.WE HAVE TO ADD -4X TO IT.SO TO BALANCE IT AND KEEP THE VALIDITY OF THE EQN.UNALTERED,WE ADD -4X TO L.H.S.ALSO.THEN ON R.H.S ,WE GET +4X-4X=0...THAT IS +4X DIAPPEARS AS WE WANTED.BUT -4X REMAINS ON L.H.S.....THIS IS THE FINAL EFFECT OF ADD AND SUBTRACT WHICH IS SUMMARISED FIRST ABOVE. \n" ); document.write( "HENCE WE GET HERE \n" ); document.write( "-9X-4X = 14-2-3 \n" ); document.write( "4.NOW SIMPLIFY BOTH SIDES COMBINING ALL UNKNOWNS ON L.H.S AND ALL KNOWNS ON R.H.S \n" ); document.write( "WE GET HERE \n" ); document.write( "-13X=9 \n" ); document.write( "5.NOW TRANSFER THE COEFFICIENT OF UNKNOWN ON L.H.S.TO R.H.S. \n" ); document.write( "APPLYING THE SAME RULE & LOGIC MENTIONED ABOVE,HERE * WILL BECOME / AND / BECOMES * \n" ); document.write( "HERE WE GET \n" ); document.write( "X = -9/13.... \n" ); document.write( "THIS IS THE ANSWER. \n" ); document.write( "6.IF YOU HAVE TIME AND WOULD LIKE TO DO....CHECK BACK THE ANSWER FOR CONFIRMATION BY SUBSTITUTION.. \n" ); document.write( "3{1-3*(-9/13)}+2=4*(-9/13)+ 14 \n" ); document.write( "3{1+27/13)+2=-36/13 +14 \n" ); document.write( "3*40/13 +2=(-36+14*13)/13 \n" ); document.write( "120/13 +2= 146/13 \n" ); document.write( "146/13 = 146/13.......OK \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
