Answer:
B
Step-by-step explanation:
So we want to find the value of x.
Note that the entire segment (JK) is the sum of the segments JI and IK. In other words:
We know that JK is (2x-1), JI is (2), and IK is (x+3). Substitute:
On the right, add:
Add 1 to both sides:
Subtract x from both sides. The right cancels:
And the value of x is 6.
Our answer is B.
