Answer:
4
Step-by-step explanation:
If the output value is 16, then the equation we are left with is
16 = 2x + 8
(because y is the output, or the answer)
To solve, first subtract 8 from both sides.
16 - 8 = 2x + 8 - 8
We get:
8 = 2x
Then simply divide 8 by 2.
4 = x
So, x = 4
The input would be 4 since x is our input.
Hope this helps!
