Hi there!
Great question!
Looks like your camera was pointing toward question 6, so I'll answer that one.
First of all, we can substitute the x for the 2, since that value is given.
So, our equation would look something like this -
[tex] \frac{14 - 2 * 2}{5} :)[/tex]
According to PEMDAS, we'll multiply the 2 by the 2. :P
2 × 2 = 4
Next, we're supposed to subtract the 14 from 4.
14 - 4 = 10
Finally, we can divide 10 by 5, which leaves us with 2, aka answer choice C. :)
Hope this helps! :D
