How long is the original length of the spring? What is the stiffness coefficient of the spring?

If the original length of the spring is l and the stiffness coefficient of the spring is k, a system of linear equations with two variables can be formulated
1=K(0.12-L)
2=K(0.14-L)
By combining the above two equations, it can be concluded that:
L=0.1m=10cm
K=50
