Hi there! :)
<u>Answer:</u>
X = 30
Y = 97
<u>Step-by-step explanation:</u>
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 = <u>3x</u> + 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 + 3<u>x</u>
y = 7 + <u>(3 × 30)</u>
y = <u>7 + 90</u>
y = 97
There you go! I really hope this helped, if there's anything just let me know! :)
