Question

Line L is segment bisector of segment QR. Find X

Answer 1

x = 5

Explanation:

since L is a segment bisector ( halves the segment ) of QR , then

MR = QM ( substitute values )

5x - 9 = 2x + 6 ( subtract 2x from both sides )

5x - 2x - 9 = 2x - 2x + 6 ( simplify )

3x - 9 = 6 ( add 9 to both sides )

3x - 9 + 9 = 6 + 9 , that is

3x = 15 ( divide both sides by 3 )

`(3)/(3)` x =
`(15)/(3)`

x = 5
