Question

solve for x.
57 = 3x + 12

Explanation:

Step1: Subtract 12 from both sides

To isolate the term with \( x \), we subtract 12 from both sides of the equation \( 57 = 3x + 12 \). This gives us \( 57 - 12 = 3x + 12 - 12 \), which simplifies to \( 45 = 3x \).

Step2: Divide both sides by 3

Now, to solve for \( x \), we divide both sides of the equation \( 45 = 3x \) by 3. So, \( \frac{45}{3} = \frac{3x}{3} \), which simplifies to \( 15 = x \).

Answer:

\( x = 15 \)
