Start with the given system
Plug in into the first equation. In other words, replace each with . Notice we've eliminated the variables. So we now have a simple equation with one unknown.
Distribute
Combine like terms on the left side
Subtract 4 from both sides
Combine like terms on the right side
Since this equation is always true for any x value, this means x can equal any number. So there are an infinite number of solutions.
