Answer:
-80
Step-by-step explanation:
We have: -6 =
+ 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 =
+ 4 - 4 ⇒ -10 = 
Then, multiply by 8 on both sides:
-10 * 8 =
* 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!

Answer:
100 in = 180 out
107 in = 187 out
117 in = 197 out
Step-by-step explanation:
we know that when there was 102 in, there was 185 out. we can also see that when there's 105 in, there was 185 out. the system outputs the input + 80
100 + 80 = 180
107 + 80 = 187
117 + 80 = 197
