<reasoning>

Identify the given equation

The problem asks us to solve the equation \(3x + 2 = x + 5\), which represents the balanced scale shown in the image.

Subtract x from both sides

To group the variable terms, we subtract \(x\) from both sides of the equation:
\[
(3x - x) + 2 = 5
\]
\[
2x + 2 = 5
\]

Subtract 2 from both sides

To isolate the variable term, we subtract \(2\) from both sides:
\[
2x = 5 - 2
\]
\[
2x = 3
\]

Solve for x

To find the value of \(x\), which represents the weight of the square, we divide both sides by \(2\):
\[
x = \frac{3}{2}
\]

Match with the options

The weight of the square is \(x = \frac{3}{2}\). This matches option B: "The square weighs \(\frac{3}{2}\)."
