If y = 3x - 1, what is the value of y when x = 3?

Explanation:
Substitute the given value into the equation. For y = 3x − 1, replace x with 3: y = 3(3) − 1. That is 9 − 1, which equals 8. So y is 8. The other numbers would come from using a different x or misapplying the subtraction, but with x = 3 you get 8.
