Simple people !
-25/27x + 8/9 = 1/3 ( original question )
-25/27x + 24/27 = 1/3 ( find a common denominator in this case 27 )
-1/27x = 1/3 ( do a simple subtraction of -25 + 24 = -1 )
-1/27 / 3/1 = x ( separate the x from the equation... -1/1 = -1 and 27/3 = 9 )
-1/9 = x ( now x has been solved ! )
-1/27 * -1/9 = 1/3 ( now the -1/27x is like saying -1/27 * x or -1/27 * -1/9 )
-1/27 / 9/-1 = 1/3 ( invert to cancel out... -1/-1 = 1 and 27/9 = 3 )
1/3 = 1/3
