Best ResponseYou've already chosen the best response.0Originally I thought there was an ordered pair or 5, 5, but that won't work for the second equation.

Best ResponseYou've already chosen the best response.03x  2y = 5 (1) 4x + y = 14 (2) We need to make the coefficients for any variable equal(x or y). So, if we multiply equation (2) by 2 , then both equations will have same coefficients of y. Then just add both equations.. and y will be eliminated and x can be found.

Best ResponseYou've already chosen the best response.03x  2y = 5 8x + 2y = 28 then we add them to be 11x + 0y =33

Best ResponseYou've already chosen the best response.1you don't have to write 0y just 11x = 33 and then divide 11 on both sides.

Best ResponseYou've already chosen the best response.0That gives me x = 3, but that wouldn't be an ordered pair. Entering that back into the original equations won't work.

Best ResponseYou've already chosen the best response.1did you solve for y?

Best ResponseYou've already chosen the best response.14x + y = 14 plug x = 3 back in this equation and solve for y

Best ResponseYou've already chosen the best response.012 + y = 14 12 on both sides y = 2 okay, then the pair is 3,2.

Best ResponseYou've already chosen the best response.1because right now you have (3, ?) we need y ... yes (3,2)

Best ResponseYou've already chosen the best response.0That still doesn't work if you put them into 3x2y = 5.

Best ResponseYou've already chosen the best response.14x + y = 14 4(3)+2=14 12+2=14 14=14 it works

Best ResponseYou've already chosen the best response.0oh wait, I accidentally put in 3(2) and  2(3)

Best ResponseYou've already chosen the best response.1take a break from math... that's where mistakes pop up... by over doing them.
