In a rhombus opposite angles are equal and adjacent angles are supplementary. So the angle opposite 108 is also 108, and the two remaining angles are 180 − 108 = 72.

If 3z + 9 is the angle opposite 108, and −2y + 4 and −x + 1 are the two adjacent angles, then
3z + 9 = 108 => 3z = 99 => z = 33,
−2y + 4 = 72 => −2y = 68 => y = −34,
−x + 1 = 72 => −x = 71 => x = −71.

If your diagram places the algebraic expressions differently (which one is opposite the 108), tell me the placement and I’ll adjust the equations.
