Question

NEED HELP Solve: 3x + (2 - 4x); when x = 5 *

Answer 1

Answer:

-3

Step-by-step explanation:

3x5=15

+1(2-4x5)=2-20-18

15-18=-3

Answer 2

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!
