There are 6 such triples.
There are infinitely many pairs of positive integers that satisfy the equation x - y = 42, starting with (43, 1), (44, 2), (45, 3) and so on.
That will depend entirely on the equation which has not been given.
7
You substitute the value of the variable into the equation and simplify. If the rsult is a true statement then that value of the variable really does satisfy the equation.
45
There are an infinite number of positive integers that satisfy the equation x^4 + y < 70.
The question does not contain an equation nor an inequality. There cannot, therefore be any ordered pairs which can satisfy an expression.
The question cannot be answered unless a specific equation is cited.
The first three positive integers, 1, 2, and 3, satisfy this condition.
There are infinitely many pairs of positive integers that satisfy the equation x - y = 42, starting with (43, 1), (44, 2), (45, 3) and so on.
I am sorry but the question is incomplete. You have not mentioned the ordered pairs and the equation is incomplete as well.
3x
Of the 729 numbers that satisfy the requirement of positive integers, 104 are divisible by 7.
There are an infinite number of ordered pairs that satisfy the equation.
The question does not contain an equation nor an inequality. There cannot be any ordered pair which can satisfy an expression.
There are infinitely many ordered pairs. One of these is (0, 0).
That will depend entirely on the equation which has not been given.
