Quick Q&A Before You Revise
When should I use substitution instead of elimination?
Use substitution when one variable can be isolated quickly. Use elimination when coefficients can be matched easily by multiplying the equations.
How do I know whether a pair has no solution?
If a1/a2 = b1/b2 but c1/c2 is different, the two lines are parallel and the system has no solution.
