Full solution stays hidden until you ask for it.
1. Compare coefficients of the variable to eliminate.
2. Choose a multiplier that makes them opposites.
3. Apply the multiplier to every term of that equation.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Multiplier applied only to one term instead of whole equation.
