1 answer

To solve the equation \( 3x + 4 = 13 \), follow these steps:

  1. Subtract 4 from both sides to isolate the term with \( x \): \[ 3x + 4 - 4 = 13 - 4 \] This simplifies to: \[ 3x = 9 \]

  2. Divide both sides by 3 to solve for \( x \): \[ \frac{3x}{3} = \frac{9}{3} \] This simplifies to: \[ x = 3 \]

Therefore, the correct order of operations to solve the equation \( 3x + 4 = 13 \) is:

  • Subtract 4, and then divide by 3.

So the correct answer from your options is: Subtract 4, and then divide by 3.
