Answer 1

[(6x137-364:i):7+139]:3=834-751
(6x137-364:i):7+139=83x3
(6x137-364:i):7 =249-139
(6x137-364:i):7 =110
6x137-364:i =  110x7
822-  364:i  =770
364:i =822-770
 i=364:52
 i=7

Answer 2

[(6x137-364:i):7+139]:3=834-751
[(822-364:i):7+139]:3=83
(822-364:i):7+139=83×3
(822-364:i):7+139=249
(822-364:i):7=249-139
(822-364:i):7=110
822-364:i=110×7
822-364:i=770
364:i=822 - 770
364:i= 52
i = 364 : 52 
i = 7
