Questions: Solve for (x) : [ 2 x+5+2=5 x= ]

Transcript text: Solve for $x$ : \[ \begin{array}{l} |2 x+5|+2=5 \\ x= \end{array} \]

Solution

Solution Steps

To solve the equation $|2x + 5| + 2 = 5$ , we first isolate the absolute value expression by subtracting 2 from both sides. This gives us $|2x + 5| = 3$ . The absolute value equation $|A| = B$ can be split into two separate equations: $A = B$ and $A = -B$ . Therefore, we solve the two equations $2x + 5 = 3$ and $2x + 5 = -3$ to find the possible values of $x$ .

Step 1: Isolate the Absolute Value Expression

Start with the equation: $|2x + 5| + 2 = 5$ Subtract 2 from both sides to isolate the absolute value: $|2x + 5| = 3$

Step 2: Solve the Absolute Value Equation

The equation $|A| = B$ can be split into two separate equations: $A = B$ and $A = -B$ . Therefore, we have:

$2x + 5 = 3$
$2x + 5 = -3$

Step 3: Solve Each Equation

Solve the first equation: $2x + 5 = 3$ Subtract 5 from both sides: $2x = -2$ Divide by 2: $x = -1$

Solve the second equation: $2x + 5 = -3$ Subtract 5 from both sides: $2x = -8$ Divide by 2: $x = -4$

Final Answer

$\boxed{x = -1, -4}$
