Ответ:
16 + x = 4 + 4x is the required equation representing the situation.
After 4 months both the clubs will have SAME NUMBER of members.
Step-by-step explanation:
Let us assume in x months, both clubs will have same number of members.
The present members in chess club = 16
Gains a new member every month.
So, the members gained in x months = x (1) = x
So, the Total members in Chess Club after x months
= Previous Members + Addition in x months = 16 +x
The present members in Film club = 4
Gains a 4 member every month.
So, the members gained in x months = x (4) = 4x
So, the Total members in Film Club after x months
= Previous Members + Addition in x months = 4 + 4x
Now, according to question:
After x months both clubs have same members.
⇒ 16 + x = 4 + 4x
or, 16 - 4 = 4x- x
or, 3 x = 12
⇒ x = 12/ 3 = 4 , or x = 4
Hence, after 4 months both the clubs will have SAME NUMBER of members.
