Right, I have hopefully mastered simultaneous equations with 2 unknowns and I am now looking at equations with 3 unknowns. I have worked through several examples and have being able to work them out with minimal referencing of coursework.
I have an equation which I am struggling with slightly.
(EQ1) 2a - 5b + c = 1
(EQ2) a + c = 2
(EQ3) b - 3c = -3
Where should I start? I tried adding EQ2 to EQ3 to make EQ4. After multiplying EQ1 x 1(a) and EQ4 x 2(a) it didn't work out. Help would be appreciated.
Thanks again.
