You can put this solution on YOUR website! FIRST OF ALL, YOU NEED TO MULTIPLY YOUR PROBLEM BY THE NUMBERS OUTSIDE OF THE PARENTHESES ON BOTH SIDES. YOU GET THE FOLLOWING : 67.2 - 78.72X = 62.64X - 35.28 ---->>>> NEXT YOU MUST GET YOUR NUMBERS ON ONE SIDE AND YOUR LETTERS ON THE OTHER. I USUALLY PREFER LETTERS ON THE LEFT AND NUMBERS ON THE RIGHT. 1ST SUBTRACT 62.64X FROM BOTH SIDES. NOW YOU HAVE : 67.2 - 141.36X = -35.28 >>>>> NEXT, YOU SUBTRACT 67.2 FROM BOTH SIDES. NOW YOU HAVE : -141.36X = -102.48 >>>>>> NEXT YOU DIVIDE BOTH SIDES BY -141.36 >>>>> NOW YOU HAVE YOUR ANSWER >>>>>> X = 0.7249575 IF YOU HAVE ANY OTHER ?'S, E MAIL ME AT : cats7051@yahoo.com YOUR FRIEND, TERRY
