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.
