Question

(3a-2b)÷(3ab-4) when a=6 and b=-3​

Answer 1

Answer:

The answer is 28.

If a=6; b=5

What is 3a+2b?

Since the value of a and b are already given, we can now substitute it to 3a+2b.

=3(6)+2(5)

The given has two operations to be used: Multiplication and Addition.

Don’t forget to follow PEMDAS.

Let’s deal first with Multiplication before Addition.

=18+10

= 28

Therefore,

If a=6; b=5,

Then

3a+2b= 28
