okay so substitution is when we find out what a varibale is equal to using one equation, and then plug it into the other equation
OpenStudy (eyust707):
so if y = "2x + 6" that means I can take "2x +6" and exchange it for y in the top equation
OpenStudy (anonymous):
\[\LARGE a=b\quad and \quad a=c\quad \Longrightarrow b=c\]
OpenStudy (eyust707):
once you do that what do you get?
OpenStudy (anonymous):
If y = 3x + 2 and y = 2x + 6, then you can just set them equal to each other and solve 3x+2=2x+6
