in the median of a trapezoid is 8 inches, and one base is 4 inches more than the other base, find the length of the bases

Question

 My cousin got this question on a test but didn't get the right answer. She asked me about it, but I can't seem to get the right answer either. This is what I am doing to solve it  (x+4+x)/2=8

I know it's probably something really silly we are omitting, but we can't seem to figure out what it is.

We know the right answer is 6 and 10, but we don't know how to get there.

Answer 1

You started correctly. Just complete!

(x + x + 4)/2 = 8

2x + 4 = 16

2x = 12

x = 6

x + 4 = 10
