To answer this question, we can follow the next steps:

1. Subtract 17 to both sides of the equation (we apply here the subtraction property of equality):


5x+17-17=82-17\Rightarrow5x+0=65\Rightarrow5x=65

2. To isolate the variable, x, in the equation, we need to divide by 5 to both sides of the equation, as follows:


(5x)/(5)=(65)/(5)\Rightarrow(5)/(5)=1\Rightarrow x=(65)/(5)\Rightarrow x=13

We can check this result if we substitute this last value into the original equation:


5x+17=82\Rightarrow5(13)+17=82\Rightarrow65+17=82\Rightarrow82=82

The result is always TRUE.

Therefore, the value for the unknown value of x is x = 13.
