Answer:
x = 14
Step-by-step explanation:
It's given in the question that a point R lies between the two points Q and S.
Therefore, by addition postulate of segments,
QS = QR + RS
Now we substitute the values of the given segments,
3x - 5 = (35 - x) + (3x - 26)
3x - 5 = -x + 3x + 35 - 26
3x - 5 = 2x + 9
3x - 2x = 5 + 9
x = 14
Therefore, the value of x is 14.
