Answer:
PR = 82
Step-by-step explanation:
Since Q is the midpoint of PR, then
PQ = QR, that is
6x - 7 = 5x + 1 ( subtract 5x from both sides )
x - 7 = 1 ( add 7 to both sides )
x = 8
Thus
PR = PQ + QR = 6x - 7 + 5x + 1 = 11x - 6
Hence
PR = 11(8) - 6 = 88 - 6 = 82
can't be simplified or you can add you get the answer
8 -1(x+4)=2
8-x-4=2
x= 2+4-8
x=-2
