To solve the system of equations x + y = 1 and 3x - y = 11:

- Solve one equation for one variable in terms of the other variable.
- Substitute the expression obtained in step 1 into the other equation.
- Solve the resulting equation for the remaining variable.
- Use the value found in step 3 to find the value of the other variable.
- Check the solution by substituting the values into both original equations to ensure they are satisfied.
