Application questions are out to ask, creative!

The school has organized tree planting activities. It is known that there are 27 people planting trees in place a and 19 people planting trees in place B. now 20 people are sent to support. In order to make the number of people in place a twice that of place B
If x people are transferred to a, how many people are transferred to B? (just list the equation.)

Set up x people to go to a
27+X=(19+20—X)*2
X = 17 (person)
People transferred to B
20-17 = 3 (person)
