Answer:
-3
Step-by-step explanation:
Given equation for reference: 3x + (2 - 4x)
3(5) + (2 - 4(5)) is with x substituted for 5.
Next, we just follow PEMDAS like any other expression
First off, parentheses.
2 - 4(5), starting with multiplication, and then subtraction
The result of the parentheses is -18
3(5) - 18 is the result when we put that back into the expression.
Next, we multiply 3 by 5; the result being
15 - 18
Now, we just subtract 18 from fifteen, getting -3
Hope this helps!
