The diagram to the right shows a reflection across a line. Find the value of each variable.

From the diagram, we can conclude that 5x = 15, 4y = 8, and 2z - 1 = 24.From that, we solve and get x = 3, y = 2, and z = 12.5
Hope this helps!
5x = 15
x = 3 <===== x is here
4y = 8
y = 2 <===== y is here
2z - 1 = 24
2z = 25
z = 12.5 <===== z is here
