Walkthrough
Full solution stays hidden until you ask for it.
1. Add the equations to eliminate the variable with opposite coefficients.
2. Solve for the remaining variable.
3. Back-substitute to find the other variable.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Elimination that fails to combine constants correctly.
