Final answer:
To evaluate 5y - x with given values x = 3 and y = 7, substitute the values into the expression to get 5(7) - 3, which simplifies to 35 - 3, resulting in a final value of 32.
Step-by-step explanation:
To evaluate the expression 5y - x when x = 3 and y = 7, we simply substitute these values into the expression.
- First, substitute y with 7: 5(7) = 35.
- Next, substitute x with 3: 35 - 3 = 32.
Therefore, the value of 5y - x when x = 3 and y = 7 is 32.
