solve the equation 3x + 2 = 17 using the bar diagram.
the solution is x =
(type an integer or a decimal.)

Explanation:

Step1: Subtract 2 from both sides

To isolate the term with \( x \), we subtract 2 from both sides of the equation \( 3x + 2 = 17 \). This gives \( 3x + 2 - 2 = 17 - 2 \), which simplifies to \( 3x = 15 \).

Step2: Divide by 3

Now, to solve for \( x \), we divide both sides of the equation \( 3x = 15 \) by 3. So, \( \frac{3x}{3} = \frac{15}{3} \), which simplifies to \( x = 5 \).

Answer:

\( x = 5 \)
