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
