Answer:
x = 13
Step-by-step explanation:
since Q is the midpoint of PR and QR is 43, then
PR = QR * 2 ⇒ 43 * 2 = 86
PR = 9x - 31
⇒ 9x - 31 = 86
⇒ 9x = 86 + 31
⇒ 9x = 117
Divide both sides by 9 ⇒ 
⇒ <u>x = 13</u>
Answer:
x=13
Step-by-step explanation:
Q is the midpoint of PR
PQ + QR = PR
PQ= QR
PQ+QR = PR
QF + QR = PR
2QR = PR
2*43 = 9x-31
86 = 9x-31
Add 31 to each side
86+31 = 9x-31+31
117 = 9x
Divide each side by 9
117/9 = 9x/9
13 =x
