Women in space have been present and active since the beginning of human spaceflight. The first woman flew to space in 1963, two years after the first person, but it was not until almost 20 years later that more would be sent. Since then a considerable number of women from a range of countries have worked in space, though overall women are still significantly less often chosen to go to space than men and represent by 2020 only 10% of all astronauts who have been to space.By 2021 most of the 65 women who have been to space, have been United States citizens, with missions on the Space Shuttle and on the International Space Station. Other countries have had one (United Kingdom, France, South Korea, Italy) or two (USSR, Canada, Japan, Russia, China) women citizens in space, taking part in missions of programs with human spaceflight capability. Additionally one dual Iranian-US woman citizen has participated as tourist on an US mission.Women face many of the same physical and psychological difficulties of spaceflight as men. Scientific studies generally show no particular adverse effect from short space missions. It has even been concluded that women might be better suited for longer space missions.[3] The main obstacle for women to go to space remains gender discrimination.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
