Solve the following absolute value equation.

[tex]\[ \frac{10|x+8|}{5}=24 \][/tex]


Sagot :

Certainly! Let's solve the given absolute value equation step by step.

[tex]\[ \frac{10|x+8|}{5} = 24 \][/tex]

First, let's simplify the left side of the equation:

[tex]\[ \frac{10|x+8|}{5} = 2|x+8| \][/tex]

So the equation becomes:

[tex]\[ 2|x+8| = 24 \][/tex]

Now, divide both sides of the equation by 2:

[tex]\[ |x+8| = \frac{24}{2} \][/tex]

[tex]\[ |x+8| = 12 \][/tex]

Next, we need to consider the definition of the absolute value function, which tells us that:

[tex]\[ |A| = B \implies A = B \quad \text{or} \quad A = -B \][/tex]

In our case:

[tex]\[ x + 8 = 12 \quad \text{or} \quad x + 8 = -12 \][/tex]

Let's solve each of these equations separately:

1. For the first equation:
[tex]\[ x + 8 = 12 \][/tex]
Subtract 8 from both sides:
[tex]\[ x = 12 - 8 \][/tex]
[tex]\[ x = 4 \][/tex]

2. For the second equation:
[tex]\[ x + 8 = -12 \][/tex]
Subtract 8 from both sides:
[tex]\[ x = -12 - 8 \][/tex]
[tex]\[ x = -20 \][/tex]

Therefore, the solutions to the equation are:

[tex]\[ x = 4 \quad \text{or} \quad x = -20 \][/tex]

Hence:
[tex]\[ x = 4 \quad \text{and} \quad x = -20 \][/tex]

So in conclusion, the values of [tex]\( x \)[/tex] that satisfy the given equation are [tex]\( 4 \)[/tex] and [tex]\( -20 \)[/tex].
