Question

Solve the system of equations using substitution.
y = 3x + 2
y = 2x + 6

Answer 1

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

Answer 2

so if y = "2x + 6" that means I can take "2x +6" and exchange it for y in the top equation

Answer 3

\[\LARGE a=b\quad and \quad a=c\quad \Longrightarrow b=c\]

Answer 4

once you do that what do you get?

Answer 5

If y = 3x + 2 and y = 2x + 6, then you can just set them equal to each other and solve
3x+2=2x+6
