Question

find the value of x. remember to check your answer! 3x = 12 x = ?

Explanation:

Step1: Isolate x by dividing both sides by 3

To solve for \( x \) in the equation \( 3x = 12 \), we divide both sides of the equation by 3. This is because the coefficient of \( x \) is 3, and dividing by the coefficient will isolate \( x \). So we have:

$$ \frac{3x}{3} = \frac{12}{3} $$

Step2: Simplify both sides

Simplifying the left side, \( \frac{3x}{3} \) simplifies to \( x \). Simplifying the right side, \( \frac{12}{3} = 4 \). So we get \( x = 4 \).

Step3: Check the answer

To check, substitute \( x = 4 \) back into the original equation \( 3x = 12 \). The left side becomes \( 3\times4 = 12 \), which is equal to the right side. So the solution is correct.

Answer:

\( x = 4 \)
