If XY = 5x-3 and XZ=44, find x and the value of YZ
mixer [17]

The midpoint of a line divides the line into equal halves.

  • <em>The value of x is 5</em>
  • <em>The value of YZ is 22</em>

<em />

Given that:

XY = 5x -3

XZ = 44

Y is the midpoint of XZ. So:

XZ = 2 \times XY

44 = (5x - 3 ) \times 2

44 = 10x - 6

Collect like terms

10x = 44 +6

10x = 50

Divide both sides by 10

x = 5

Recall that: Y is the midpoint of XZ

This means that:

YZ = \frac12 XZ

YZ = \frac12 \times 44

YZ = 22

Hence, the value of x is 5 and YZ is 22
