x y = 2 x + 3 y,

how do I find the value of xy, for integer solutions?

Ok so if x and y are integers, which satisfy the above equation, then there are 8 values for xy: -8, -3, -1, 0, 24, 25, 27, 32. There are 8

m + n \leq x + y < m + n + 2 ⟹ ⌊ x + y ⌋ = m + n

Problems understanding proof of if

x + y = x + z

y = z

(Baby Rudin, Chapter 1, Proposition 1.14)

He didn't substitute

z

y

; rather, he substituted

x + z

x + y

. This is legitimate based on the assumption that

x + y = x + z

The line with equation

y = 4 x + c

is a tangent to the curve with equation

y = x^{2} - x - 5

https://math.stackexchange.com/questions/171451/the-line-with-equation-y-4xc-is-a-tangent-to-the-curve-with-equation-y-x2-x

y = (\frac{5}{2})^{2} - (\frac{5}{2}) - 5 = 4 (\frac{5}{2}) + c ⟹ c = - 45 / 4

4 x + c = x^{2} - x - 5 x^{2} - 5 x - (5 + c) = 0

yx+y-x=0

Trek aan beide kanten x af.

yx-x=-y

Trek aan beide kanten y af. Een waarde afgetrokken van nul retourneert de bijbehorende negatie.

\left(y-1\right)x=-y

Combineer alle termen met x.

\frac{\left(y-1\right)x}{y-1}=-\frac{y}{y-1}

Deel beide zijden van de vergelijking door y-1.

x=-\frac{y}{y-1}

Delen door y-1 maakt de vermenigvuldiging met y-1 ongedaan.

\left(x+1\right)y=x

Combineer alle termen met y.

\frac{\left(x+1\right)y}{x+1}=\frac{x}{x+1}

Deel beide zijden van de vergelijking door x+1.

y=\frac{x}{x+1}

Delen door x+1 maakt de vermenigvuldiging met x+1 ongedaan.
