Need help on this question

Answer:
x = -10
Step-by-step explanation:
If you want your "output," or y-value, to be 11, then substitute it into the formula to find your "input," or x-value.
11 = 1 - x Subtract 1 from both sides.
10 = -x Divide both sides by negative 1
-10 = x And there's your answer.
Hope this helps!
