Hi

I am trying to solve the following equation, but I'm not sure if I'm right, can anybody advise?

2x + 3y = 19

6x - 7y = -7

So far I have done the following:

4x + 6y = 38

Added the second and third equation, to get:

10x + 13y = 31

31 / 10 = 3.1

3.1 * 2 = 6.2

19 - 6.2 = 12.8 / 3 = 4.3

x = 3.1

y = 4.3

I appreciate any advice.
