The value of x for the numbers is,
⇒ x = 1.36
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The numbers are,
⇒ 7, 5, 5, 2, 8 and 7
Now, The mean of the numbers is,
⇒ (7 + 5 + 5 + 2 + 8 + 7) / 6
⇒ 34/6
⇒ 5.67
Here, Two additional numbers 2 and x, reduce the mean by 1.
We get;
⇒ (34 + 2 + x) / 8 = 5.67 - 1
⇒ (36 + x) / 8 = 4.67
⇒ 36 + x = 4.67 × 8
⇒ 36 + x = 37.36
⇒ x = 37.36 - 36
⇒ x = 1.36

(7 + 5 + 5 + 2 + 8 + 7) / 6 = 34/6 = 5.67
(34 + 2 + x) / 8 = 5.67 - 1
(36 + x) / 8 = 4.67
36 + x = 4.67 * 8
36 + x = 37.36
x = 37.36 - 36
x = 1.36
(34 + 2 + x) / 8 = 5.67 - 1
(36 + x) / 8 = 4.67
36 + x = 4.67 * 8
36 + x = 37.36
x = 37.36 - 36
x = 1.36
