Answer:

The value of x is 5.

The value of y is 4.

Step-by-step explanation:

From the figure, the lengths of the lines with equal number of markings are equal.

So, we will have the length of 7x - 4 = 31.

We solve for 'x'.

We get: 7x = 35

⇒ x = 5

Similarly, 4y + 8 = 24

⇒ 4y = 24 - 8

⇒ 4y = 16

⇒ y = 4

Therefore, the value of x = 5 and y = 4.

Hence, the answer.
