#x = 26#

Explanation:

We know that the average of #n# numbers is the sum of the numbers divided by #n#.

Therefore:

#(30 + x + 4+ 14 + 35 + x + 2 + 13 + 32 + 10)/8 = 24#

Simplifying, we get:

#30 + x + 4 + 14 + 35 + x + 2 + 13 + 32 + 10 = 192#

#2x + 140 = 192#

#x = 26#

If we check our answer, we do get an average of #24#, therefore, our answer is correct.

Hopefully this helps!
