Geometry: What is the value of X

I know the answer is x=7
I just need to know, how do you get 7 as x.
So someone pls help with the strategies+details of every step!!​

Answer 1

x = 7

Explanation:

The dashes on each side of the rectangle indicate congruency.

This means that PS = QR, or 2x - 3 = 11.

Now we would solve for this like normal.

2x - 3 = 11 add 3 to each side

+ 3 + 3

--------------

2x = 14 now divide by 2 to find x

÷ 2 ÷2

--------------

x = 7
