To evaluate the expression \(2(x + 4) - 3y\) when \(x = 5\) and \(y = 4\), you substitute the values of \(x\) and \(y\) into the expression:

\(2(5 + 4) - 3 \cdot 4\)

Now simplify the expression by performing the operations step by step:

First, calculate the value inside the parenthesis:
\(5 + 4 = 9\)

Then multiply that by 2:
\(2 \cdot 9 = 18\)

Next, multiply 3 by \(y\), which is 4:
\(3 \cdot 4 = 12\)

Now subtract the second result from the first one:
\(18 - 12 = 6\)

Therefore, the value of the expression \(2(x + 4) - 3y\) when \(x = 5\) and \(y = 4\) is \(6\).
