Question

Evaluate the expression when B = 5 and Y = -3.9b - y

Answer 1

We are given the following expression

$9b-y$

Where the values of b and b are given by

b = 5 and y = -3

Let us substitute these values into the expression

$\begin{gathered} 9b-y \\ 9\cdot5-(-3) \\ 45+3 \\ 48 \end{gathered}$

Therefore, the expression is simplified to 48
