Answer:
This means x equals zero
Explanation:
For example when I have: 3x + 5 = 5, my next step would be to subtract the 5 from both sides;
I end up with 3x = 5 - 5;
Then I get 3x = 0
After this I divide the 3 to both sides to isolate the x on one side.
x = 0/3
Whenever a zero is on the numerator of a fraction it equals zero, whenever the zero is on the denominator it is undefined and this is a mathematical error.
x = 0
-15 (0) = 0
