Two plus two is equal to four
The given matrix represent the following linear system
4x - 7y = -12
-14x + 4y = 4
Good luck!!!
The answer is C
I pretty sure
427+316
step one- add 400 and 300=700
step two- take 3 from the 16 and add it to the 27 and add - 27+3+13=43
step three- add 43 and 700
I think that the common core way just adds more steps and makes it more complicated than just adding it regularly, but that's just me.
