1 answer:
Vladimir [108]3 years ago
8 0

Answer:

x=5

y=4

Step-by-step explanation:

The sides with the 2 bars are equal  so

7x-4 = 31

Add 4 to each side

7x-4+4 = 31+4

7x = 35

Divide each side by 7

7x/7 = 35/7

x =5


The sides with 3 bars are equal

4y+8 = 24

Subtract 8 from each side

4y+8-8 = 24-8

4y = 16

Divide by 4

4y/4 = 16/4

y =4
