I heard this was the place to come for help! I guess I heard wrong This question has been out here for over an hour 4x-x/4+x+1/3
zysi [14]
Don't be snarky !

<u>4x - x/4 + x + 1/3 = 2x</u>

Add up the 'x' terms on the left side:  (4 + 1/4 + 1)x = 5-1/4 x = 21/4 x

Now the equation is:      21/4 x + 1/3 = 2x

2x is the same as  8/4 x .  Subtract it from each side:

13/4x + 1/3 = 0

Subtract  1/3  from each side :

13/4 x = - 1/3

Multiply each side by 4 :

13 x = - 4/3

Divide each side by 13 :

<em>x =</em>  (- 4/3) / (13)  = <em>- 4 / 39</em>
