Answer 2

• See below

Explanation:

We assume Q is between P and R.

According to segment addition postulate we have:

• PQ + QR = PR

Substitute values and solve for x:

• 7x - 3 + 32 -2x = 59
• 5x + 29 = 59
• 5x = 30
• x = 6

Find PQ:

• PQ = 7*6 - 3 = 42 - 3 = 39 units

Find QR:

• QR = 32 - 2*6 = 32 - 12 = 20 units
