Given

  • PQ = QR . . . . . . Q is the midpoint of PR
  • PQ = 3x+14
  • QR = 7x-10

Find

  • x

Solution

Put the given expressions in the given relation.

... 3x +14 = 7x -10

Subtract the left side.

... 0 = (7x -10) -(3x +14)

... 0 = (7-3)x +(-10-14) . . . . . simplify

... 0 = 4x -24

Divide by the coefficient of x.

... 0 = x - 6

Add the opposite of the constant.

... 6 = x

The value of x is 6.
