    An equation has only one equal (=) sign. I don't know what the = $365 means. Are you sure you copied the equation correctly?

    I'll attempt the solution by ignoring the $365.

    x+(x-25)=2(x-25)

    Firse, since a + precedes the group on the left side of the equation, simply remove the parentheses. Nothing changes.

    x+x-25=2(x-25)

    Distribute (multiply) the 2 across the difference (x-25) on the right side.

    x+x-25=2x-50

    Combine terms on the left side.

    2x-25=2x-50

    Subtract 2x from both sides.

    2x-25-2x=2x-50-2x

    -25=-50

    This is a false statement. Therefore the equation has no solution. I feel like there's an error in the way you presented your problem. Check it and re-post if necessary.
