Answer:
x=4
y=23/4
Step-by-step explanation:
The one line means it is the same length as the other side with the one line.
The two lines means it is the same length as the other side with the two lines.
7x-4 =24
Add 4 to each side
7x-4+4 = 24+4
7x = 28
Divide by 7
7x/7 = 28/7
x = 4
The three lines means it is the same length as the other side with the three lines.
4y+8 = 31
Subtract 8 from each side
4y +8-8 = 31-8
4y = 23
Divide by 4
4y/4 = 23/4
y = 23/4
