Question

40-9y=? y=2 whats the anwser here?

Answer 1

We want to know the value of the expression:

`40-9y`

when y=2. For doing so, we will replace the value onto the expression, by multiplying it by 9, and then substracting to 40 the result. This is,

`\begin{gathered} 40-9y=40-9(2) \\ =40-18 \\ =22 \end{gathered}`

So, the value of the expression is 22.
