Answer 2

Answer:

5 – (3x + 4)

5 – 1(3x) – 1(+4)

5 – 3x – 4

5 – 4 – 3x

1 – 3x

Now I can solve in the usual manner:

1 - 3x = 1

-1 -1

-----------

-3x = 0

--- --

-3 -3

x = 0

Is "x = 0" a valid solution? Yes, indeed, it is, because zero is a valid number. It's not that the solution is "nothing"; it's that the solution is "something", and that this "something" is zero. So my answer is:

x = 0

Students can generally become comfortable with zero being the solution to an equation, but the difference between a solution of "zero" (that solution being a numerical value) and "nothing" (being possibly a physical measure of something like "no apples" or "no money") can cause confusion.

Please make sure that you understand that "zero" itself is not "nothing". Zero is a numerical value which (in "real life" or in the context of a word problem) might imply that there is "nothing" of something or other, but zero itself is a real thing; it exists; it is "something".
