Solve: |2 + 4x| 11

erastovalidia [21]

Correct option is A) [-13/4, 9/4] .

Step-by-step explanation:

Here we have following equation as |2 + 4x| = 11 or , $|2 + 4x| = 11$ . We need to solve for the value of x .Let's find out:

We know that Modulus Function is both positive & negative for particular values of x , i.e.

|2 + 4x| is positive :

⇒ $|2+4x|=11$

⇒ $2+4x=11$

⇒ $4x=9$

⇒ $x = \frac{9}{4}$

|2 + 4x| is negative :

⇒ $|2+4x|=11$

⇒ $-2-4x=11$

⇒ $-4x=13$

⇒ $x = \frac{-13}{4}$

Therefore , Correct option is A) [-13/4, 9/4] .

The answer to the question provided is 10.

Step-by-step explanation:

☆Cross multiply.

$\frac{2x + 5}{20} = \frac{x + 5}{12} \\ \\ 20(x + 5) = 12(2x + 5) \\ \: \: \: \: \: \: \: \: \: \: 20x + 100 = 24x + 60 \\ \frac{ - 24x \: \: \: \: \: \: \: \: \: \: = - 24x}{ - 4x + 100 = 60} \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: \: \: - 100 = - 100}{ \frac{ - 4x}{ - 4} = \frac{ - 40}{ - 4} } \\ x = 10$
