Solve the linear system by substitution
WebEXAMPLE ONE Solve by substitution 2x + 5y = – 5 y = –x – 5 x = – 3y + 3 5x – 9y = 3 We can also solve linear systems by the process of elimination. In elimination, we want the coefficient of one of the variables to be OPPOSITES. This way, when we add the equations together, it will be eliminated! WebExample. Solve the following system of equations by substitution. −x+y=−5 2x−5y =1 − x + y = − 5 2 x − 5 y = 1. Show Solution. In the following video, you will be given an example of …
