I do not understand this or how to do it

okay i gotchu

x = 8, Both PQ and QR equal 41. And PR = 82.

Step-by-step explanation:

PQ = 6x- 7

QR = 5x + 1

Since we know that Q is the midpoint, PQ and QR are equivalent.

To find the value of x, we need to set them equal to each other and solve for x.

6x - 7 = 5x + 1

6x = 5x + 8

x = 8.

Now plug x into either to find what both equal

6(8) -7 = 48- 7 = 41.

5(8) + 1 = 40+ 1 = 41.

41 = 41.

PR is just the total distance, 41+ 41 = 82. So, PR = 82.

Hope this helps

but which class are u may know that first
