We are given that x = 3 and y = 8.

So,

1. x + 2y

Plug in the value of x and y which is given above in the equation. That is replace x with 3 and y with 8 to get the result of the expression.

3 + 2*8 ----> Just replaced x with 3 and y with 8.

Now calculating the above expression to get the result.

3 + 16

19 ----> which is the answer.

That is x + 2y = 19 when the value of x is 3 and value of y is 8.

2. -4(y - x)

Plug in the value of x and y which is given above in the ...
