86390 + 7483-(?) + 4720 - 27910 = 78814​

Answer 1

Answer:

78814-7483=71331 is your answer

Answer 2

Answer:

Therefore, x = -8131

Step-by-step explanation:

Given the question is

86390 + 7483- (?) + 4720 - 27910 = 78814

We will find the value of (?)

Let us consider (?) = x

then

86390 + 7483 - (x) + 4720 - 27910 = 78814

(86390 + 7483 + 4720) -x - 27910 = 78814

98593 - x - 27910 = 78814

70683 - x = 78814

-x = 78814 - 70683

-x = 8131

x = -8131

Therefore, x = -8131

Hence the ? = -8131.
