Hi there! :)
Answer:
X = 30
Y = 97
Step-by-step explanation:
The lines on each side of the figure means that the side with 1 line is equal to the other side with 1 line and the side with 2 lines is equal to the other side with 2 lines.
Let's start by the sides with 1 line:
4x = 3x + 30
Now solve this equation by isolating "x":
4x = 3x + 30
Subtract 3x from each side of the equation: 4x - 3x = x
x = 30
Now that you know the value of "x", you can go ahead and find the value of "y" by replacing the "x" in the expression of the side with 2 lines and isolating the equation by isolating "y":
y = 7 + 3x
y = 7 + (3 × 30)
y = 7 + 90
y = 97
There you go! I really hope this helped, if there's anything just let me know! :)
