Step-by-step explanation:

first clear all the brackets and clearly see the symbols also.

when you will  clear the brackets you have to multiply the symbols.

then you have plus the common ones .

after  doing plus or minus you have to have to bring the common ones on one side by changing the sign also but only the numbers which will remove from its position.

then do the plus or minus and then divide them and the answer will come in mixed fraction.
