x = a/13x=a13

Explanation:

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

9x + 2a - 2a + 4x = 3a - 4x - 2a + 4x9x+2a2a+4x=3a4x2a+4x

9x + 4x + 2a - 2a = 3a - 2a - 4x + 4x9x+4x+2a2a=3a2a4x+4x

13x + 0 = 1a + 013x+0=1a+0

13x = a13x=a

(13x)/13 = a/1313x13=a13

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

x = a/13
