Answer:

x = 11

Step-by-step explanation:

The mean is found by adding all the numbers and dividing by the number of numbers

x is the unknown number

(3+5+7+9+x)/5 = 7

Multiply each side by 5

(3+5+7+9+x)/5 *5 = 7*5

(3+5+7+9+x) = 35

Combine like terms

24+x = 35

Subtract 24 from each side

24+x-24 = 35 -24

x = 11
