Answer: -15
Step-by-step explanation:
8 - (-5) - 4(7)
Order of operations: PEMDAS: we multiply/divide before adding/subtracting, so:
8 - (-5) - 28 (multiply out 4 * 7)
8 + 5 - 28 (when you subtract a negative number, the negative cancels out, so you add a positive; x - (-y) = x + y)
13 - 28 = -15 (carry out subtraction and get result)
