Question: Solve the indicated or given systems of equations by an appropriate algebraic method. A spring of length L is stretched x cm for each newton

Solve the indicated or given systems of equations by an appropriate algebraic method.

A spring of length L is stretched x cm for each newton of weight hung from it. Weights of 3 N and then 5 N are hung from the spring, leading to the equations
L + 3x = 18 L + 5x = 22 Solve for L and x.

L + 3x = 18 L + 5x = 22
