For this case we have the following expression:

[tex]6a-5b[/tex]

We must evaluate the expression when:

[tex]a = -3\\b = 4[/tex]

Then, replacing the values we have:[tex]6 (-3) -5 (4)[/tex]

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

[tex]+ * - = -[/tex]

So:

[tex]-18-20 =[/tex]

Equal signs are added and the same sign is placed:

-38

Answer:

-38
