Find the value of y required for
Ulleksa [173]

This is algebra disguised as geometry.  I object.  There are much better ways to combine algebra and geometry.

Anyway, in a parallelogram the diagonals meet at their midpoints, so bisect each other.  So we have two pairs of congruent segments; geometry over.

3x + 1 = x+27

79 - y = 2y + 22

We can ignore the one about x.

79 - 22 = 2y + y

57 = 3y

y = 19

Answer: 19
