Help chaps I am having a bad time with this.
I can appreciate this is basic, however i can not get my head around it.
Im scrubbing up on my maths as i was thinking of doing a HND in Engineering. I am working my way through K.A. Stroud's Engineering Mathematics and simply can't get to grips with this.
the exercise question is:-
2a - 5b + c = 1
a + c = 2
b - 3c = -3
solve the equations for a,b and c.
Im just not sure on the golden rules? do i use substitution or elimination? If someone can guide me through this it would be of HUGE appreciation.
Great site by the way:)
