HOW is a coordinate pair ordered?

Use Substitution, to solve the system of equations:  $$y=2x+1$$  

$$y=-x+16$$  

Use Substitution, to solve the system of equations

$$y=x+6$$   $$y=3x$$  

Use Substitution, to solve the system of equations y = 2x + 1 y = 4x - 1

Use Substitution, to solve the system of equations

y = -2x + 5 y = 2x - 11

Solve using the substitution method.

x + y = 12

x = 2y

Using Substitution, solve for the following system of linear equations:  $$y=x+3$$  

$$y=-2x-3$$
