Answer:

x = -3

x= -7

Explanation:

l x + 5 l = 4/2

(x + 5) = 2 or - (x + 5) = 2

- (x + 5) - 5 = 2 - 5

x = -3

- x - 5 = 2

- x - 5 + 5 = 2 + 5

-x = 7

x = -7

Answer:

x = -7
x = -3

Explanation:

Given the following question:


2\left|x+5\right|=4

To find the answer to this question we have to remember to apply the absolute value. The absolute value means we have to convert any negative within the lines into positive.


2\left|x+5\right|=4

(2\left|x+5\right|)/(2)=(4)/(2)

\left|x+5\right|=2
Apply absolute value:

x+5=-2

x+5=2
Solve each equation:

x+5=-2

5-5=0

-2-5=-7

x=-7

x+5=2

5-5=0

2-5=-3

x=-3


Your answers are "x = -3 and x = -7."

Hope this helps.
