Question

Set A and set B are described as A = { 2, 4, 3y, 8 } and B = { x : x is an even number and x < 10 }. Given that set A and set B are equal. Find the value of y.
Set A dan set B adalah dihuraikan sebagai A = { 2, 4, 3y, 8 } dan B = { x : x ialah nombor genap dan x < 10 }. Diberi set A dan set B ialah set yang sama. Cari nilai y.

Answer 1

Step-by-step explanation:

A={2,4,3y,8}

set B is x is an even number and x is less than 10

so even number less than 10 are 2 ,4 ,6 ,8

set A and B are equal

so 3y = 6

y=2
