Is linear combination the same as elimination ??

I think so but I'm not sure.

In order to combine, you have to multiply the top equation by 2
so you get
8g  + 10h  =  8
8g  -  10h  =  4
---------------
16g            =  12
g = 3/4 --> plug it in to solve for h
8(3/4)-10h = 4
6-10h=4
10h=2
h=1/5

Your result: g=3/4, h=1/5

I agree with BTaylor....that is exactly the way I would do it :)
