What is the value of x in the equation 2x + 8 = 20?

• A. A) 6
• B. B) 5
• C. C) 9
• D. D) 4

Answer: (A)

To find the value of \( x \) in the equation \( 2x + 8 = 20 \), we start by isolating \( 2x \). This can be achieved by subtracting 8 from both sides of the equation: \[ 2x + 8 - 8 = 20 - 8 \] This simplifies to: \[ 2x = 12 \] Next, to solve for \( x \), we divide both sides of the equation by 2: \[ x = \frac{12}{2} \] This leads to: \[ x = 6 \] Hence, the correct answer is 6, which corresponds to the first choice. This solution demonstrates the proper method of isolating the variable and performing basic arithmetic operations to arrive at the correct answer.

To find the value of ( x ) in the equation ( 2x + 8 = 20 ), we start by isolating ( 2x ). This can be achieved by subtracting 8 from both sides of the equation:

[

2x + 8 - 8 = 20 - 8

]

This simplifies to:

[

2x = 12

]

Next, to solve for ( x ), we divide both sides of the equation by 2:

[

x = \frac{12}{2}

]

This leads to:

[

x = 6

]

Hence, the correct answer is 6, which corresponds to the first choice. This solution demonstrates the proper method of isolating the variable and performing basic arithmetic operations to arrive at the correct answer.
