how do i simplify this?

I am working under the premise that x-2/3 does NOT mean (x-2)/3...

7 +- [2(x+1) - 3(x-2/3)]

7 +- (2x + 2 - 3x + 2)

7 +- (2x -3x + 2 + 2)

7 +- (4-x)

Two possibilities:

7 + (4-x) = 11 - x

7 - (4-x) = 7 -4 + x = 3 +x

11-x and 3+x

7 +- [2(x+1) - 3(x-2/3)]

7 +- (2x + 2 - 3x + 2)

7 +- (2x -3x + 2 + 2)

7 +- (4-x)

Two possibilities:

7 + (4-x) = 11 - x

7 - (4-x) = 7 -4 + x = 3 +x

11-x and 3+x
