thanks a lot

Answer 1

ok, i get it now:

x=y+yx

Answer 2

"a number x is y more than a number y times x"

Let's break it into parts.

"a number y times x" = y*x

"a number x is y more" x - y, because x = ___ + y

Now put it together.

x - y = y*x
x = y*x + y

Now factor out y:
x = y*(x+1)
y = x / (x+1)

Now you have y in terms of x. Solutions to y and x cannot be found without another equation.

Answer 3

this is the answer in my book: x=y+yx
