Answer:

x = 3, y = 5

Step-by-step explanation:

As per the diagram we got:

FH = GH = EH

As FH = 7x + 4 and EH = 9x - 2, we solve the following equation for x:

7x + 4 = 9x - 2
9x - 7x = 4 + 2
2x = 6
x = 3

So each segment is:

7*3 + 4 = 25

Therefore:

5y = 25
y = 5

So the variables are:

x = 3, y = 5
