Answer by doukungfoo(195)   (Show Source): You can put this solution on YOUR website!is this your problem? x+4=3x first move all terms with x to one side of the equation this is done by subtracting x from both sides x-x+4=3x-x 0+4=2x 4=2x now divide both sides by 2 4/2=2x/2 2=x now check the answer in the original equation x+4=3x 2+4=(3)(2) 6=6 So the answer is x=2 Answer by edjones(7569)   (Show Source): You can put this solution on YOUR website!(x+4)/4=3x/36 (x+4)/4=x/12 3(x+4)=x 3x+12=x 2x=-12 x=-6 If you CHECK ALL your problems by replacing x with your answer you will find your mistakes and learn a lot. you would be surprised how many of my mistakes I find checking. (-6+4)/4=-6*3/36 -1/2=-1/2 Ed
