#x = a/13#

Explanation:

To solve this problem you must perform the necessary math to isolate the #x# terms on one side of the equation and the #a# terms on the other side of the equation while keeping the equation balanced:

#9x + 2a - 2a + 4x = 3a - 4x - 2a + 4x#

#9x + 4x + 2a - 2a = 3a - 2a - 4x + 4x#

#13x + 0 = 1a + 0#

#13x = a#

#(13x)/13 = a/13#

#(cancel(13)x)/cancel(13) = a/13#

#x = a/13#
