we can see that a = 2. so it's 2 + 4/2 = 2+2 = 4

the answer is 2
a = 2
since (a+4)/2 = (a+4)a
then a must be 2 since a is in the same part of the equation on the other side

a = 2
subtract a from both sides 4/2 = 4/a
fairly obvious from there

a+4/2 = a + 4/a
a + 2 = a + 4/a
a + 2 -a = 4/a
2 = 4/a
2a = 4
a = 4/2
a = 2
--------

a+4/2=a+4/a
a+2=a+4/a
and then you times all of it by a
a2(a square)+2a=a2 (a square)+4
a2-a2=4-2a
0=4-2a
-4=-2a
a=2
