What is the value of x in the equation 3x = 18?

Explanation:
To find the value of \( x \) in the equation \( 3x = 18 \), you need to isolate \( x \). This involves performing the same operation on both sides of the equation. Start by dividing both sides of the equation by 3: \[ 3x / 3 = 18 / 3 \] This simplifies to: \[ x = 6 \] Thus, the correct value of \( x \) is 6. This means when 3 is multiplied by 6, the result equals 18, satisfying the original equation. Overall, this process of isolating the variable while maintaining equality in the equation is fundamental in algebra, helping understand how to manipulate equations to find unknown values.

To find the value of ( x ) in the equation ( 3x = 18 ), you need to isolate ( x ). This involves performing the same operation on both sides of the equation.

Start by dividing both sides of the equation by 3:

[

3x / 3 = 18 / 3

]

This simplifies to:

[

x = 6

]

Thus, the correct value of ( x ) is 6. This means when 3 is multiplied by 6, the result equals 18, satisfying the original equation.

Overall, this process of isolating the variable while maintaining equality in the equation is fundamental in algebra, helping understand how to manipulate equations to find unknown values.
