2/3 x - 1/5 x = x - 1

Change the fractions to have the same denominators:

10/15 x - 3/15 x = 15/15 x - 1

Simplify the left side of the equation:

7/15 x = 15/15x - 1

Get everything to the right side of the equation:

0 = 8/15 x - 1

Move the (1) to the left side:

1 = 8/15x

Multiply 15 to both sides:

15 = 8x

Divide both sides by 8

15/8 = x

Answer is x=8/15
