Can anyone help please

y = 5

Solution:

In the triangle WXZ, WY is the perpendicular bisector of XY.

XY = YZ

Perpendicular bisector theorem:

If a point is on the perpendicular bisector of a line segment, then it is equidistant from the end points of the line segment.

By the above theorem,

WX = WZ

2y + 7 = 5y – 8

Add 8 on both sides of the equation.

2y + 15 = 5y

Subtract 2y from both sides of the equation.

15 = 3y

Divide by 3 on both sides of the equation.

5 = y

Switch the sides.

y = 5
