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

-3

Step-by-step explanation:

3x5=15

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

15-18=-3

-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!

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
