Answer:
-19
Explanation:
If c = -4 and y = 3, replace c and y with their corresponding values in the expression, so that the expression will look like this: (-4) - (5 * 3).
Since multiplication comes before subtraction in PEMDAS, you would multiply 5 by 3, which gets you 15.
Now the expression is (-4) - (15). Then, you do the subtraction. -4 - 15 is equal to -19.
Does that help?
