Had a quick search but can't find what I need, so I'll make a new thread instead.
I've got a quick problem here that I can't get my head around, and it's the only simultaneous equation out of 10 that I can't solve, I keep getting answers that satisfy one or the other!
(solving from 1)
(subtract 2y from both sides)
(divide by 3 to find x)
(substituting into into 2)
(multiply both sides by 3 to remove denominator)
(subtract 32 from both sides, )
Which leaves me with which of course then does not satisfy the equation very well... I've gone over my working and isolated the problem to this point, I hope it's not something glaring, but what have I done wrong?
