Let's solve your equation step-by-step.
2a−8a=12−8a
Step 1: Simplify both sides of the equation.
2a−8a=12−8a
2a+−8a=12+−8a
(2a+−8a)=−8a+12(Combine Like Terms)
−6a=−8a+12
−6a=−8a+12
Step 2: Add 8a to both sides.
−6a+8a=−8a+12+8a
2a=12
Step 3: Divide both sides by 2.
2a
2
=
12

Answer:
a jet stream that brings alternating warm and cold periods
Explanation:
Jet streams are known as a composition of powerful wind that normally moves from west to east all over the world.
According to various research, it is considered strongest in winter, specifically showing a strong effect on weather in North America.
A jet stream at a normal pace is associated with normal cold and occasional warms, but at a strong pace, it usually creates heavy cold moving and warmth from north to south and vice versa. This is known as Rossby waves.
Hence, in North America, a winter weather change that might be associated with large amplitude Rossby waves is " a jet stream that brings alternating warm and cold period"
