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
