We want to start by multiplying everything in the brackets by what’s on the left outside of it, in this case, 5.
We then get 5*2x = 10x (we want to be careful to keep the variable at this point) and then we can multiply 5*(-4) — we write 4 as a negative because we are given a subtraction sign and that makes it a negative number (if we were given “+4” then the number would be positive).
We can then get the equation:
10x-20-2y
Now, we can input the values given for x and y:
10(-2)-20-2(6)
And then we can put that in our calculator and get -52.
