Answer:

Value of given expression x is -4

Step-by-step explanation:

Given equation in question;

4 + 2|3x + 4| = -4

Find:

Value of given expression

Computation:

4 + 2|3x + 4| = -4

Using BODMAS rule;

⇒ 4 + 2|3x + 4| = -4

⇒ 2|3x + 4| = - 4 - 4

⇒ 2|3x + 4| = - 8

⇒ |3x + 4| = - 8 / 2

⇒ |3x + 4| = - 4

⇒ 3x + 4 = - 8

⇒ 3x = -8 - 4

⇒ 3x = -12

⇒ x = -12 / 3

⇒ x = -4

Value of given expression x is -4

Answer:

The correct answer is 31x + 0.5

Step-by-step explanation:

∵ 13x + 5 + 17x - 4.5 + x

To solve this correctly you must to add the coefficients of the like terms (terms who has same variables or constant terms)

∵ 13x , 17x , x are like terms ⇒ terms with same variable

  (same letters and same power)

∵ 5 , 4.5 are like terms ⇒ constant terms (numbers only)

∴ (13x + 17x + x) + (5 - 4.5) = 31x + 0.5

* <u>The error of first answer:</u>

- 18x + 17x - 4.5 + x

- She add 13x + 5 = 18x ⇒ she add unlike terms

* <u>The error of second answer:</u>

- 35x - 4.5 + x

- She add 13x + 5 + 17x  = 35x ⇒ she add 2 like terms with 1 unlike term

* <u>The error of third answer:</u>

- 30.5x + x

- She add 13x + 5 + 17x - 4.5 = (13x + 17x) + (5 - 4.5) =

  30x + 0.5 ⇒ she add 2 like terms and 2 constant terms

  and then add the 2 unlike answers

* <u>The error of fourth answer:</u>

- 31.5x

- She add 13x + 5 + 17x - 4.5 + x = (13x + 17x + x) + (5 - 4.5) =

  31x + 0.5 ⇒ she add 3 like terms and 2 constant terms

  and then add the 2 unlike answers
