For this case we have the following expression:

6a-5b

We must evaluate the expression when:

a = -3\\b = 4

Then, replacing the values we have:6 (-3) -5 (4)

Taking into account that according to the law of the signs of multiplication, it is fulfilled that:

+ * - = -

So:

-18-20 =

Equal signs are added and the same sign is placed:

-38

Answer:

-38
