10y + 2 + 2y = 14 simplfy
What is y = 1? combine like terms 12y = 14 - 2 then 12y = 12 then y = 1
400
3x + 3y = 27 and x - 3y = -11 when using elimination gives you x = 4, what variable was eliminated?
What is y?
400

Solve y = -2x + 2 and y = -2x - 2
What is No Solution - Parallel Lines
500
Solve with Substitution y = 2x and x + y = -24
What is (-8, -16)? x + y = -24 so x + 2x = -24 then 3x= -24 and x=-8 now get y = 2x so y = 2(-8) and y = -16
