Your task is to make all four lines work out arithmetically by replacing the 16 ◯’s below with the following 16 digits.  Can you complete it?

0    0    1    2    2    2    2    4    4    5    5    6    6    7    7    8

◯  +  ◯   =     6     =   ◯  +  ◯
◯  +  ◯   =     5     =   ◯  –  ◯
◯  +  ◯   =    12    =   ◯  ×  ◯
◯  +  ◯   =     7     =   ◯  ÷  ◯
