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