Please help me with this! <3

Answer 1

Think of x(symbol)y as a function like f(x)=3x-y. Since the first symbol we see is in parenthesis, we know that x=-1 and y=-2. Plug that into f(x), and you get 3(-1)-(-2)=-1. So know we have the x value for the second symbol, which is -1, and the y value, which is seen to the right: (-3). Plug that back into f(x), and you get 3(-1)-(-3)= 0. Your answer should be A: 0.
