Answer:
<h2><u><em>
9</em></u></h2>
Step-by-step explanation:
the mean is 6 (write on the picture)
so
(7 + 3 + 5 + x) : 4 = 6
(15 + x) : 4 = 6
15 + x = 24
x = 24 - 15
<u><em>x = 9</em></u>
<u><em>--------------------------------</em></u>
check
(7 + 3 + 5 + 9) : 4 = 6
24 : 4 = 6
6 = 6
the answer is good
