\\(\\textrm{Use the inverse operation.}\\)
22,000-17,456 =4,544
v = 4,544/45,671= 0.099
1,456,908 + 445,112 n = 756,123 n+990,897
1,456,908 - 990,897 = 756,123 n- 445,112 n
466,011 = 311,011n
1.498 = n

\\(\\textrm{Use the inverse operation.}\\)
Take the unit digit as x and the tens digit as 10x as they have the same digit.
8893,760 p -,1,456,321p -2,789,653 = 9,090,932
8,893,760 p -,1,456,321p = 9,090,932 + 2,789,653
7,437,439 p = 11,880,585
p = 11,880,585/ 7,437,439
p= 1.5974
