Start with the second equation
Divide both sides by 2
Break up the fraction
Reduce
Now let's solve the system
by substitution
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.
Combine like terms on the left side
Add 8 to both sides
Combine like terms on the right side
Since this equation is never true for any y value, this means there are no solutions.
