If 3x = 15, what is the value of x?

Explanation:
To find the value of \( x \) in the equation \( 3x = 15 \), you want to isolate \( x \) by dividing both sides of the equation by 3. Starting with the equation: \[ 3x = 15 \] You can divide both sides by 3: \[ \frac{3x}{3} = \frac{15}{3} \] This simplifies to: \[ x = 5 \] This process shows that if you have a variable multiplied by a constant (in this case, 3), dividing both sides by that constant will give you the value of the variable. Thus, the value of \( x \) is 5, confirming that the answer is correct.

To find the value of ( x ) in the equation ( 3x = 15 ), you want to isolate ( x ) by dividing both sides of the equation by 3.

Starting with the equation:

[

3x = 15

]

You can divide both sides by 3:

[

\frac{3x}{3} = \frac{15}{3}

]

This simplifies to:

[

x = 5

]

This process shows that if you have a variable multiplied by a constant (in this case, 3), dividing both sides by that constant will give you the value of the variable. Thus, the value of ( x ) is 5, confirming that the answer is correct.
