To solve the system of equations:

- Start by isolating the variable in one equation.
- Substitute the expression for that variable into the other equation.
- Solve the resulting equation for the remaining variable.
- Once you have found the value of one variable, substitute it back into one of the original equations to find the value of the other variable.
