SOLUTION: Solve the system by addition.Provide the x and the y values as a coordinate 5x - 3y = 13 4x - 3y = 11 I tried this but I think it is incorrect: 3/5x -3y =13 5y = 13 3 3

Question 122478: Solve the system by addition.Provide the x and the y values as a coordinate
5x - 3y = 13
4x - 3y = 11
I tried this but I think it is incorrect:
3/5x -3y =13
5y = 13
3 3

Answer by algebrapro18(249) (Show Source): You can put this solution on YOUR website!
5x - 3y = 13
4x - 3y = 11

first thing you need to do is multiply the bottom equation by -1.

-1(4x - 3y = 11)
-4x + 3y = -11

now you need to and the two equations together.

5x - 3y = 13
-4x + 3y = -11
---------------
x = 2
now that you have a value for x plug that into the first equation and solve for y.

5(2) - 3y = 13
10 - 3y = 13
-3y = 3
y = -1

so the answer as a coordinate is (2, -1).
