Question 1168069: 3x+y=5 4x-y=2
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! 3x + y = 5
4x - y = 2
add the equations together to get 7x = 7
solve for x to get x = 1
in the first equation, replace x with 1 and solve for y.
3x + y = 5 becomes 3 + y = 5
subtract 3 from both sides of the equation to get y = 5 - 3 = 2
you have x = 1 and y = 2
replace x and y with those values in the second equation to get 4*1 -2*y = 2.
simplify to get 4 - 2 = 2, which is true.
solution is confirmed to be good and is x = 1 and y = 2
