Question

What is the solution to this system of equations? {2x+4y=227x+y=12{2x+4y=227x+y=12?

Answer 1

For this case we have the following system of equations:

`2x + 4y = 227 x + y = 12`
Rewriting we have:

`2x + 4y = 227 -4x - 4y = -48`
Adding equations we have:

`-2x = 179`
Clearing x:

`x = - 179/2 x = -89.5`
Then, we look for the value of y:

`x + y = 12 y = 12 - x y = 12 - (-89.5) y = 12 + 89.5 y = 101.5`
Answer:
The solution to the system of equations is:
x = -89.5
y = 101.5
