What happened after 2 hours on the surface of Venus?

If you were to venture there without any gear, you would survive for less than 2 minutes, provided that you held your breath! Visiting Venus would be like landing inside of an oven. The temperature on its surface is approximately 400C. Its surface pressure is also about 90 times greater than that of Earth.

Explanation:

Your question is confusing because it is past-tense. Please clarify more clearly. Thanks!

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
