Determine the value of x when f(x) = 8. f(x) = 7 1 − x What is the value of x when f(x) = 8?

x=63

Step-by-step explanation:

If f(x)=8 and f(x)=71-x, these can be set equal to eachother

71 - x = 8

Subtract 71 from both sides to isolate the variable

- x = -63

divide both sides by -1 because the variable can not be negative

x = 63

hope this helps! :)

(x, y)→(x − 8, y − 7)
