Q1 ALGEBRA
The number of positive integer valued pairs (x, y) satisfying 4x-17y = 1 and x <= 1000 is
a. 59
b. 57
c. 55
d. 58Y = (4x-1)/17
The integral values of x for which y is an integer are 13, 30, 47,...
The values are in the form 17n +13, where n >= 0
17n+13 <1000
17n <987
n<58.05
n can take values from 0 to 58=> Number of values = 59Write Here
