Evaluate - 6 (x-2y) when x = - 3 and y = - 5

a. - 42

b. 80

c. - 80

d. - 16

A because - 6 x - 3 is 18 and - 2 x - 5 is 10 x - 6 is - 60 so - 60 + 18 = - 42

Simply substitute x for - 3 and y for - 5, creating the equation shown below:

-6 (-3 - 2 (-5))

Now that you have your values set up, now you can do the math by starting off with Multiplying - 2 by - 5, which will get you 10.

Now that you have the parenthesis simplified in the parenthesis, you can use the distributive property by multiplying all the numbers with - 6, like so:

-6 (-3+10) = 18 - 60, which simplifies to - 42, in which (A) is your answer.
