Question

6a - 5b when a = -3 and b = 4

Answer 1

Given.

6a - 5b

Plug in values.

6(-3) - 5(4) =

-18 - 20 =

-38

Answer 2

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
