Answer:

x=89

Explanation:

We can plug into the formula for the mean to get
(87+73+84+82+x)/5=83 .

We can combine like terms on the left side to get
(326+x)/5=83 .

We can multiply by
on both sides to get
326+x=415 .

We can finally subtract
326 from both sides to get
x=89 .

So, the answer is
$\boxed{x=89}$ and we're done!
