For this case we have the following system of equations: [tex]2x + 4y = 227
x + y = 12[/tex] Rewriting we have: [tex]2x + 4y = 227
-4x - 4y = -48[/tex] Adding equations we have: [tex]-2x = 179
[/tex] Clearing x: [tex]x = - 179/2
x = -89.5[/tex] Then, we look for the value of y: [tex]x + y = 12
y = 12 - x
y = 12 - (-89.5)
y = 12 + 89.5
y = 101.5[/tex] Answer: The solution to the system of equations is: x = -89.5 y = 101.5
