See:

-25/27x + 8/9 = 1/3
-25/27x + 24/27 = 9/27
-25x = 9 - 24 9-24 is not 15, rather it is -15 <------------
25/27x = 15/27
x = 15/25
x = 3/5

Now let's test my number with the original equation:

-25/27 * 3/5 + 8/9 = 0.3(3) which is 1/3 Watch your placement of x and order of operations<-----------------

P.S. In Russia we were learning even more complicated square equations (you know ax^2 + bx + c = 0 where a <> 0) in the 4th grade (10 years old), so were learning the equations like solved above when we were even younger.
