7/9-4x+3x=2/9+x
Simplify the expression...
7/9-x=2/9+x
now group the x and the numbers each to one side...
2x=7/9-2/9
2x=5/9
divide by 2...
x=5/18

put the variable on one side and the other numbers on the other then u get
7/9 - 2/9 = 4x-3x+x
5/9 = 2x (divide by 2 on both sides)
x = 5/18

Seems to be simple algebra.
Subtracting the x terms on the left, 7/9 - x = 2/9 + x
Adding x to both sides, 7/9 = 2/9 + 2x
Subtracting 2/9 from both sides, 5/9 = 2x
Dividing both sides by 2, x = 5/18
If this or another answer here proves helpful in your research, you can encourage good answers by choosing one answer as the "best answer."

7/9-4x+3x=2/9+x?
7/9 -1x=2/9+x
Times both sides by 9... 7-9x=2+9x
thats enough
