Answer:
12+m=85
Explanation:
m+85= 12 In this m would be equal to-73. It has nothing related to the statement above.
12-m= 85 If a number would have to be subtracted from 12 then the answer would have to be with a negative sign. (-)
12m= 85 12m can be written as 12*m
12+m= 85 is the correct answer.
