Answer 3

Ok, I see it now.

Answer 4

Line 1 is correct. It is just the word problem translated into an equation.

Answer 5

Since on the left side of line 1 there is a 4 being subtracted, you need to add 4 to both sides.
Now look at line 2. Does it look like 4 was added to both sides?

Answer 6

i need to find the error

Answer 7

Here is the equation of line 1 which is correct.

Answer 8

Here is what line 2 should have looked like.
When you add 4 to the left side, you must also add 4 to the right side.
Now compare my line 2 with the problem's line 2.
They did not add 4 to the right side of the equation. That is the error.
