Answer:

42

Step-by-step explanation:

First Method

In this case we will substitute w=8 directly into the expression and solve:

[tex]7w - 14[/tex]

When x=8, we get:

[tex]7(8) - 14[/tex]

This gives us:

[tex]56 - 14 = 42[/tex]

Second Method:

This time we factor

[tex]7w - 14 = 7(w - 2)[/tex]

when w=8,

[tex]7(8 - 2) = 7 \times 6 = 42[/tex]
