Question

What is the value of the expression below when z, equals, 7z=7 and w, equals, 4w=4?
4, z, plus, w
4z+w

Answer 1

To evaluate the expression \( 4z + w \) given \( z = 7 \) and \( w = 4 \), we can substitute the values of \( z \) and \( w \) into the expression.

1. Start with the expression:
\[
4z + w
\]

2. Substitute \( z = 7 \) and \( w = 4 \):
\[
4(7) + 4
\]

3. Calculate \( 4(7) \):
\[
4 \times 7 = 28
\]

4. Now, add \( 4 \) to \( 28 \):
\[
28 + 4 = 32
\]

Thus, the value of the expression \( 4z + w \) when \( z = 7 \) and \( w = 4 \) is \( \boxed{32} \).
