The number of new members in the choir this year is 27 members

Given:

Number of members = 36

Let

x = new members

y = returning members

x = 3y

Total members = new members + returning members

36 = x + y

substitute x = 3y into 36 = x + y

36 = x + y

36 = 3y + y

36 = 4y

divide both sides by 4

y = 36 / 4

y = 9

Therefore,

x = new members

x = 3y

x = 3 × 9

x = 27

y = returning members

y = 9
