In mathematics, the Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part

. Many consider it to be the most important unsolved problem in pure mathematics (Bombieri 2000). It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by Bernhard Riemann (1859), after whom it is named.
x => Hamburgers
y => Hot dogs
x + y = 26
3.5x + 2y = 70
-2x - 2y = -52
3.5x + 2y = 70
-----------------------
1.5x = 18
x = 18 / 1.5 = 12
y = 26 - 12 = 14
They sold 12 hamburgers and 14 hot dogs
24 pens divided by 2 boxes equals 12 pens per box.
Solve the following system using elimination:
{x - 2 y = -23 | (equation 1)
{x - y = 7 | (equation 2)
Subtract equation 1 from equation 2:
{x - 2 y = -23 | (equation 1)
{0 x+y = 30 | (equation 2)
Add 2 × (equation 2) to equation 1:
{x+0 y = 37 | (equation 1)
{0 x+y = 30 | (equation 2)
Collect results:
Answer: {x = 37 , y = 30
