Thread: simultaneous equation

hi, can anyone figure out the solution to

4x + 3y = 17 and y = 3/4x - 19/4

and if possible can you show me exactly how you figure it out step by step?

thanks for any help

ah, in case anyone was in the process of writing a reply to this, i just realised that the answer must be x = 5 and y = -1.

sorry for any inconvenience

Replace y in the first equation:





Now find y.
