Hmm, seems like they tried to get sneaky with the variable placement.  

The first thing you need to to is distribute 2/5 through the parenthesis.  This gives you the equation:

2/5x-4/5=4x

Now, get x on one side of the equation:

-4/5=3 3/5x (note the mixed number)

x=-2/9 (negative because we're dividing a positive and negative number) 

Answer:

[tex]-\frac{2}{9}[/tex]

Step-by-step explanation:

Our equation is

[tex]\frac{2}{5}(x-2)=4x[/tex]

Multiplying both sides by 5 we get

[tex]2(x-2)=5*4x\\2x-4=20x[/tex]

bringing 2x to other side of = sign

[tex]-4=20x-2x\\18x=-4[/tex]

dividing both sides by 18

[tex]x=\frac{-4}{18}\\x=-\frac{2}{9}[/tex]
