Given : M is the mid point of XY
Prove : XY = 2* XM
M is the midpoint if XY - Given
XM ≈ MY - Definition of congruence
XM = MY - definition of congruence
XM + MY = XY - Segment addition postulate
XM + XM = XY - substitution postulate of equality
2 * XM = XY - Multiplication property of equality
XY = 2 * XM - simplify
Is this right?

looks good, as long as you are careful to distinguish between the line segment XM and its measure.
