-4.7-(-4.7) = 0 ???

Right. The two negative signs makes a postive sign and they cancel out and equal 0. Good job.

Thanks

To solve this equation, we can simplify it step by step.

First, let's simplify the expression inside the parentheses. We have `-4.7 - (-4.7)`. To subtract a negative number, we can rewrite it as addition. Thus, `-4.7 - (-4.7)` is the same as `-4.7 + 4.7`.

Next, we can proceed with the addition. -4.7 plus 4.7 equals 0.

Therefore, the answer to this equation is 0.
