can you please rewrite the question?

sure @FriedRice

anonymous · Answer

im not sure if the equation 3x - 1= (8x - 2) = 4 is correct

@FriedRice  its supposed to be 1/2 like .50

anonymous · Answer

oh but is there suppose to be 2 equal signs 3x - 1/2 = (8x - 2) = 4

anonymous · Answer

or one of them has to be a plus sign?

anonymous · Answer

This is what it looks like @FriedRice

anonymous · Answer

ohh ok now it makes more sense thanks

anonymous · Answer

No Problem :]

anonymous · Answer

$$3x -\frac{ 1 }{ 2 }(8x - 2) = 4$$

anonymous · Answer

first you must distribute
$$3x - 4x + 1 = 4$$

anonymous · Answer

then you must subtract or add common terms
$$-x + 1 = 4$$

anonymous · Answer

or x = -3

anonymous · Answer

so from the statement what do you think is wrong or its all correct?

anonymous · Answer

So the sign was wrong it was supposed to be negative?

anonymous · Answer

yes so the from the explanation from the question step 2 made the mistake

anonymous · Answer

I don;t understand what is happening in step 3 though because a number comes in that wasnt there before.

anonymous · Answer

well its just subtracting both sides

anonymous · Answer

its not adding a number

anonymous · Answer

its just subtracting the original number and then moving the number to the other side

anonymous · Answer

Ohh I see because im usually used to it being subtracted vertically.
