`a)` `x - 3/5 = 2/3`

`=> x = 2/3 + 3/5`

`=> x = 10/15 + 9/15`

`=> x = 19/15`

`b)` `x - 1/3 = 1/2`

`=> x = 1/2 + 1/3`

`=> x = 3/6 + 2/6`

`=> x = 5/6`

`c)` `2/3 - x = (1/3)^2`

`=> 2/3 - x = 1/9`

`=> x = 2/3 - 1/9`

`=> x = 6/9 - 1/9`

`=> x = 5/9`

`d)` `x + 0,5 = 3/4`

`=> x + 1/2 = 3/4`

`=> x = 3/4 - 2/4`

`=> x = 1/4`

`e)` `2/5 - sqrtx = 1/4`

`=> sqrtx = 2/5 - 1/4`

`=> sqrtx = 8/20 - 5/20`

`=> sqrtx = 3/20`

`=> x = (3/20)^2`

`=> x = 9/400`

`f)` `3sqrtx + 1 = 40`

`=> 3sqrtx = 39`

`=> sqrtx = 13`

`=> x = 13^2`

`=> x = 169`

`g)` `3/5 - x = -1/4 + 7/10`

`=> 3/5 - x = -5/20 + 14/20`

`=> 3/5 - x = 9/20`

`=> x = 3/5 - 9/20`

`=> x = 12/20 - 9/20`

`=> x = 3/20`

`h)` `3/4 - (x - 2/3) = 5/6`

`=> x - 2/3 = 3/4 - 5/6`

`=> x - 2/3 = 9/12 - 10/12`

`=> x - 2/3 = -1/12`

`=> x = -1/12 + 2/3`

`=> x = -1/12 + 8/12`

`=> x = 7/12`

`i)` `-4/3x - 1/2 = 1,25`

`=> -4/3x - 1/2 = 5/4`

`=> -4/3x = 5/4 + 1/2`

`=> -4/3x = 5/4 + 2/4`

`=> -4/3x = 7/4`

`=> x = 7/4:(-4/3)`

`=> x = 7/4*(-3/4)`

`=> x = -21/16`
