What is the condition of outside air at a certain time and place?​

Weather describes what the atmosphere is like at a specific time and place, and may include temperature, wind, and precipitation.

Explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
