Hey!
Alright, we'll first plug in the value of [tex]x[/tex] 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 [tex]x[/tex] equals -18, is -98.
Hope this helps!
