A student factors $24x + 18y$ as $6(4x + 3y)$ . Which statement
checks whether this is correct?

Multiply $6$ back into $(4x + 3y)$ : $6 \cdot 4x + 6 \cdot 3y = 24x + 18y$ . Since this matches the original expression, the
factoring is verified.

Add $6 + 4x + 3y$ and check whether the sum equals $24x + 18y$ .

Divide $24x + 18y$ by $4x + 3y$ and check whether the quotient
is a whole number.

Substitute $x = 0$ into both expressions and check whether they
both equal $18y$ .
