Answer:

-80

Step-by-step explanation:

We have: -6 = \frac{x}{8} + 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 = \frac{x}{8} + 4 - 4  ⇒  -10 = \frac{x}{8}

Then, multiply by 8 on both sides:

-10 * 8 = \frac{x}{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
