____________________________________
Explanation:
____________________________________
To calculate the mean:
____________________________________
The mean =
{the sum of all the values in the number set} ÷
{the number of values in the data set} ;
____________________________________
To solve for "x" ;
____________________________________
Given that the "mean" is: "8" ;
____________________________________
8 = { 3 + 7 + 9 + 12 + x } / 5 ;
____________________________________
↔ { 3 + 7 + 9 + 12 + x } / 5 = 8 ;
____________________________________
→ { 3 + 7 + 9 + 12 + x } = 8 * 5 ;
____________________________________
→ { 31 + x } = 40 ;
____________________________________
↔ x + 31 = 40 ;
____________________________________
Subtract "31" from EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x" ;
____________________________________
→ x + 31 − 31 = 40 − 31 ;
→ x = 9 .
