2A + C = 8
A + 3C = 9
Multiply second equation by 2.
2A + 6C = 18
Subtract first equation from revised second.
5C = 10
Work it from there.
A + 3C = 9

2a + c = 8
a + 3c = 9
I suggest substitution, from #1, let c = 8-2a
plug into #2
a + 3c = 9
I suggest substitution, from #1, let c = 8-2a
plug into #2
