If x and y can take only natural number values, find the number of (x,y) pairs satisfying the equation 2X + 5 = 100.

Answer 1

Given equation is 2x + 5 = 100.

Subtracting 5 from both sides:

2x = 95

Dividing by 2:

x = 95/2 = 47.5

Since x can only take natural number values, there are no pairs of natural numbers (x, y) that satisfy the equation 2x + 5 = 100.
