Question

Solve by the linear combination method (with or without multiplication).

4g + 5h = 4
8g – 10h = 4

Answer 1

Is linear combination the same as elimination ??

Answer 2

I think so but I'm not sure.

Answer 3

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

Answer 4

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