What is the value of the expression below when w, equals, 5*w*=5 and x, equals, 9*x*=9?

7, w, minus, x

7*w*−*x*

The value of the expression \( 7w - x \) when \( w = 5 \) and \( x = 9 \) is 26.

Would you like more details or have any questions? Here are 5 related questions:

1. How would the result change if \( x \) were doubled?
2. What is the value of \( 7w + x \) with the same values for \( w \) and \( x \)?
3. How would you solve the equation \( 7w - x = 0 \) for \( w \) when \( x = 9 \)?
4. What is the result if \( w = 6 \) instead of \( 5 \) while keeping \( x = 9 \)?
5. How would you express \( w \) in terms of \( x \) in the equation \( 7w - x = 26 \)?

**Tip:** Always plug in the values carefully to ensure accuracy when evaluating expressions.
