Answer:
6
Step-by-step explanation:
We are given the expression:

and asked to evaluate when w=9, x=7, and y=1.
The variables w and x are not included in the expression, so we only have to focus on the variable y.
y is equal to 1, so we can plug 1 in for y.


Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
First, multiply 11 and 1.
11*1=11

Next, subtract 5 from 11.

The expression 11y-5 when evaluated for y=1 is equal to 6.
