    A brute-force approach with max_it equal to maximum size works for all test-cases:

    import os

def kangaroo(x1, v1, x2, v2):
    it = 0
    max_it = 10000
    while x1 != x2:
        x1 += v1
        x2 += v2
        if it == max_it:
            return 'NO'
        it += 1
    return 'YES'
    
if __name__ == '__main__':
    fptr = open(os.environ['OUTPUT_PATH'], 'w')

    first_multiple_input = input().rstrip().split()

    x1 = int(first_multiple_input[0])

    v1 = int(first_multiple_input[1])

    x2 = int(first_multiple_input[2])

    v2 = int(first_multiple_input[3])

    result = kangaroo(x1, v1, x2, v2)

    fptr.write(result + '\n')

    fptr.close()
