Question

Evaluate the expression when a= - 5 and y=3 a-6y  and .

Answer 1

To evaluate the expression \( a - 6y \) given \( a = -5 \) and \( y = 3 \), substitute the values of \( a \) and \( y \) into the expression:

\[
a - 6y = -5 - 6(3)
\]

Now calculate \( 6(3) \):

\[
6(3) = 18
\]

Substituting back in gives you:

\[
-5 - 18
\]

Now perform the subtraction:

\[
-5 - 18 = -23
\]

Therefore, the value of the expression \( a - 6y \) when \( a = -5 \) and \( y = 3 \) is \( \boxed{-23} \).
