Question

Find the value X and Y

Answer 1

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! :)
