Hey!


Alright, we'll first plug in the value of
x in the equation.

Original Equation :
5x - 8

New Equation {Added Variable Value} :
5( -18 ) - 8

We'll start off by removing the parenthesis from the equation.

Old Equation :
5( -18 ) - 8

New Equation {Parenthesis Removed} :
-5 · 18 - 8

And now we multiply -5 and 18.

Old Equation :
-5 · 18 - 8

New Equation {Changed by Multiplying -5 and 18} :
-90 - 8

The next step is to simply subtract.

Old Equation :
-90 - 8

Solution {Old Equation Solved} :
-98

So, the answer to the equation 5x - 8, where
x equals -18, is -98.

Hope this helps!
