Answer:
17
Step-by-step explanation:
The first thing to do is plug in the numbers for the equation. Starting with:
[-20-(-3)]/(19-20)
When you answer that you simplify the answer to
(-20+3)/(19-20)
You answer what is in the parenthesis first.
(-17)/(-1)
After this step you simplify.
17.
The answer is seventeen because any number over 1 is just the number. For example, 3/1=3. The answer is positive because the negative in the numerator and denominator cancel eachother out. leaving the answer as 17.
