Question

How many integer values of x & y satisfy the expression 4x+7y=3 where |x|<1000 and |y|<1000​

Answer 1

Answer:

Since the minimum value of x is -999, the minimum value of (x + 1) is -998. Also, since the maximum value of x is 999, the maximum value of (x + 1) is 1000. There are 285 integer values of x and y that satisfy the expression 4x + 7y = 3. Hope this helps!.
