Systems of 3 equations:
I keep getting trapped on practice questions for problems that ask to solve for one variable and have three equations with three variables. I can grind through substitution, but it takes me 5 minutes to do so. Does anyone have any good tricks for these problems, to get the answer quickly and accurately.
