Answer:
or
Step-by-step explanation:
We use casework on when and when
.
For the first case, , we add 9 to both sides to get
.
Dividing both sides by 3 gives
For the second case, , we add 9 to both sides to get
.
Dividing both sides by 3 gives
.
Checking both cases, we plug in and
.
For the first case, we have , which satisfies the equation.
For the second case, we have , which also satisfies the equation.
This gives us two solutions to the equation; and
.
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:
Y is the midpoint of XZ. So:
Collect like terms
Divide both sides by 10
Recall that: Y is the midpoint of XZ
This means that:
Hence, the value of x is 5 and YZ is 22
