3 0

Answer: 1/2

Step-by-step explanation:

30x + 18 = 35-4x

collecting like terms

30x + 4x = 35-18

34x = 17

divide both sides by 34

34x/34 = 17/34

x = 1/2

taurus [48]
Let the total number of people surveyed by y.

to find the percentage of a number in terms of decimals or integers, just multiply the total by the percentage,
so with this question, 
y x 40% = 20
shift x40% to the other side and turn it into /40%
y = 20 / 40%
change the percentage into decimals for easier calculations,
y = 20 / 0.4
y = 50

therefore, the answer to this is 50 people.
