To find the value of the expression \( x(y - 3z) \) using the given values \( x = 3 \), \( y = -4 \), and \( z = 2 \), we first need to calculate \( y - 3z \).

1. Start with \( z \):

- Since \( z = 2 \), we calculate \( 3z \):

\[ 3z = 3 \times 2 = 6 \]

2. Now substitute this back into the expression for \( y - 3z \):

- We already have \( y = -4 \):

\[ y - 3z = -4 - 6 \]

\[ y - 3z = -10 \]

3. Now that we have \( y - 3z = -10 \), we multiply this by \( x \):

- We substitute \( x = 3 \):

\[ x(y - 3z) = 3 \times -10 = -30 \]

Therefore, the correct value of the expression \( x(y - 3z) \) is \( -30 \), which means the choice is indeed consistent with this
