Answer 2

Arrange the second equation first. and multiply first eq with 0.5

Answer 3

arrange in the same order as the first one

Answer 4

0.15g-0.9f=-5.55
0.9f+0.15g=5.55 <---like this so now we have this

0.18f-0.3g=3 (multiply by 0.5)
0.9f+0.15g=5.55

Answer 5

f = –7, g = 5

f = –5, g = –7

f = 5, g = 7

f = 5, g = –7

Answer 6

f=-5 ,g=-7
