Question 39158: How do you do systems by elimination?
Answer by fractalier(6550)   (Show Source):
You can put this solution on YOUR website! The idea is to add or subtract equations in such a way that the adding or subtracting eliminates one of the variables. That makes the systems easier to solve. If we start with three equations and three unknowns, we try to "boil it down" to two equations, two unknowns, and then further to one equation, one unknown...give us a problem and someone here will show you how...
