Title: Solving linear systems by substitution and elimination Post by: theepicseal on Dec 18, 2020 May someone solve the questiona below for me? I’m having difficulty on how to go about solving this as I’m not familiar with solving equations in this format.
1) solve the following linear system by substitution. x + 2y + 2 = 0 2x -6y + 9 = 0 2) solve the following linear system by elimination. 3x + 2y = 8 2x + 3y = 7 Thank you :) Title: Re: Solving linear systems by substitution and elimination Post by: bio_man on Dec 18, 2020 Here's the answer to the first one using substitution technique:
