Step by step:
(2+3+7+10+15+x)/6 = 8
Simplify
(37+x)/6 = 8
Multipy both sides by 6 to isolate the variable
37+x = 8 * 6
(the asterix is a multiplication sign)- Simplify
37+x = 48
Subtract 37 on both sides to isolate the variable
x =11
(2+3+7+10+15+x)/6 = 8

37+x = 8 * 6
(the asterix is a multiplication sign)- Simplify

(3 + 7 + 11 + x)/4 = 9
21 + x = 9 × 4 = 36
