What is the value of x in the equation 2(x - 3) = 12?

• A. 9
• B. 6
• C. 12
• D. 3

Answer: (A)

To find the value of x in the equation 2(x - 3) = 12, we can start by simplifying the equation. First, distribute the 2 on the left side of the equation: 2 * (x - 3) = 12 This gives: 2x - 6 = 12 Next, to isolate the term with x, we can add 6 to both sides of the equation: 2x - 6 + 6 = 12 + 6, which simplifies to: 2x = 18 Now, to solve for x, divide both sides by 2: x = 18 / 2 This results in: x = 9 Therefore, the value of x is 9. This solution shows how basic algebraic manipulation can be applied to solve for an unknown variable in an equation.

To find the value of x in the equation 2(x - 3) = 12, we can start by simplifying the equation.

First, distribute the 2 on the left side of the equation:

2 * (x - 3) = 12

This gives:

2x - 6 = 12

Next, to isolate the term with x, we can add 6 to both sides of the equation:

2x - 6 + 6 = 12 + 6,

which simplifies to:

2x = 18

Now, to solve for x, divide both sides by 2:

x = 18 / 2

This results in:

x = 9

Therefore, the value of x is 9. This solution shows how basic algebraic manipulation can be applied to solve for an unknown variable in an equation.
