Evaluate the expression when b = 6 and y = -4. -6y + b

Sure, let's evaluate the expression step by step.

The expression is -6y + b.

Step 1: Substitute the given values of b and y into the expression. So, we replace b with 6 and y with -4.

This gives us: -6*(-4) + 6

Step 2: Simplify the expression.

Multiplication comes before addition in the order of operations (PEMDAS/BODMAS), so we do the multiplication first.

-6 * -4 = 24

So, the expression becomes: 24 + 6

Step 3: Now, we do the addition.

24 + 6 = 30

So, the value of the expression -6y + b when b = 6 and y = -4 is 30.
