Answer :
BIDMAS first
4 x 9 = 36
36 - 26 = 10
To double check we do the other side
2 x 9 = 18
18 - 8 = 10
10 = 10
4x9=36 (Multiplication before Addition)
then,36-26 which is 10
On the other side, 2x9=18 (Multiplication before Addition)
and 18-8=10
=> 1st side= 2nd side
then,36-26 which is 10
On the other side, 2x9=18 (Multiplication before Addition)
and 18-8=10
=> 1st side= 2nd side
