Follow this simple formula,
2 + 7 = 2 x 10 + 2 x 7 = 20 + 14 = 34
8 + 9 = 9 x 10 - 9 x 8 = 90 - 72 = 18
6 + 3 = 6 x 10 + 3 x 6 = 60 + 18 = 78
Similarly we have,
5 + 7 = 7 x 10 - 7 x 5 = 70 - 35 = 35
Hope This Helps You!

2+7=(2×10)+(2×7)=34
8+9=(9×10)−(9×8)=18
6+3=(6×10)+(6×3)=78
Hence 5+7=(7×10)−(7×5)=35
