Just doing a bit of math homework and I am stuck on 2 questions
the first one is a similtanoius equation and goes like this
y = x - 1
y = x2 -3
ive been trying for about half an hour and all i end up with is
y = (square root of) y - 2
im not sure if it's right, it does not look it.
the 2nd question i don't know the name of and looks like
72x = 49
i don't even know where to begin on that, i just have to factorise it.
thankyou in advanced
