Question

evaluate the expression when b=-5 and y=3

b-7y

Answer 1

To evaluate the expression \( b - 7y \) when \( b = -5 \) and \( y = 3 \), you can substitute the given values into the expression:

\[
b - 7y = -5 - 7(3)
\]

Now calculate \( 7(3) \):

\[
7(3) = 21
\]

Now substitute this back into the expression:

\[
-5 - 21
\]

Now perform the subtraction:

\[
-5 - 21 = -26
\]

Therefore, the value of the expression \( b - 7y \) when \( b = -5 \) and \( y = 3 \) is \(-26\).
