    True for all x.

    Step-by-step explanation:

    1. Expand 1/3 (6-9x)

    2-3x

    2. Expand - 1/5 (15x-10)

    -3x+2

    3. Subtract 2 from both sides.

    2-3x-2 = - 3x+2-2

    4. Simplify.

    -3x = - 3x

    5. Add 3x to both sides.

    -3x + - 3x = - 3x + - 3x

    6. Simplify.

    0=0

    Both sides are equal, so it is true for all x.
