Evaluate the expression below when x = 9 and y = 12

Question

4(x+6)-3(y+4)

Answer 1

To evaluate the expression \(4(x+6)-3(y+4)\) when \(x = 9\) and \(y = 12\), we start by substituting the values of \(x\) and \(y\) into the expression:

\[
4(9+6)-3(12+4)
\]

Next, perform the operations inside the parentheses:

\[
4(15)-3(16)
\]

Then, carry out the multiplication:

\[
60 - 48
\]

Finally, subtract to get the result:

\[
60 - 48 = 12
\]

So, when \(x = 9\) and \(y = 12\), the value of the expression \(4(x+6)-3(y+4)\) is \(12\).
