Answer:
37
Step-by-step explanation:
Let's use the rule GEMDAS (Grouping, Exponents, Multiply, Divide, Add, Subtract) from left to right. Therefore, we will simplify the equation in the parentheses.
. -(-7) creates a double negative, deeming the 7 positive, because when there is two negatives the number will turn into a positive.
= 49, -3 x 4= -12. Therefore the final form of the equation will be 49 - 12 = 37.
