Since T is the midpoint of PQ, this means that PT and TQ must be equal to each other. Make them equal to each other in an equation.

PT = TQ

4x + 2 = 7x - 7

  • Subtract 2 from both sides.

4x = 7x - 9

  • Subtract 7x from both sides.

-3x = -9

  • Divide both sides by -3.

x = 3

  • Now substitute 3 for x into PT.

PT = 4(3) + 2

  • PT = 12 + 2

PT = 14
