Question

evaluate the expression when $a = -3$ and $b = 6$. $a - 5b$

Explanation:

Step1: Substitute the values of a and b

We know that \( a = -3 \) and \( b = 6 \). Substitute these values into the expression \( a - 5b \). So we get \( (-3)-5\times(6) \).

Step2: Perform the multiplication

First, calculate \( 5\times6 = 30 \). Now the expression becomes \( -3 - 30 \).

Step3: Perform the subtraction

Subtract 30 from -3: \( -3-30=-33 \).

Answer:

\( -33 \)
