Question

The sum of a number m and 39 is 10

Answer 1

Answer:

m = -29

Step-by-step explanation:

converting the words into mathematical expressions:

"sum of number m and 39" ---> m + 39

"sum of number m and 39 is 10" -----> m + 39 = 10

solving for m

m + 39 = 10   (subtract 39 from both sides)

m = 10 - 39

m = -29
