Hi I have two questions that I need help on.

Solve Graphically

(a) 2x – 3y = 11/12 and x + y = -7/12

(b) y = 30 – 6x + 2x2 and y = 2(x + 11)

Im really not sure how to do this at all and would apppreciate any help. I've never hadany experience before solving simultaneous equations graphically so please if you wouldn't mind be detailed. Thanks
