If , find the values of a and b.

Given:

To find: values of a and b

By the definition of equality of ordered pairs, we have and simultaneously solving for a and b

and

⇒ b = 1

⇒ a = 2

If (x + 1, 1) = (3y, y - 1), find the values of x and y.

If the ordered pairs (x, - 1) and (5, y) belong to the set {(a, b): b = 2a - 3}, find the values of x and y.

If a ∈ { - 1, 2, 3, 4, 5} and b ∈ {0, 3, 6}, write the set of all ordered pairs (a, b) such that a + b = 5.

If a ∈ {2, 4, 6, 9} and b ∈{4, 6, 18, 27}, then form the set of all ordered pairs (a, b) such that a divides b and a<b.
