Wll give brainlist i sincerely don't even know where to begin here.

y = 5

Step-by-step explanation:

WY is the perpendicular bisector of XZ and so divides ΔWXZ into 2 congruent triangles ΔWXY and ΔWZY

Hence WZ = WX ← corresponding sides, thus

5y - 8 = 2y + 7 ( subtract 2y from both sides )

3y - 8 = 7 ( add 8 to both sides )

3y = 15 ( divide both sides by 3 )

y = 5
