Question

Solve using the addition principle. -25+n=12

Answer 1

Answer: n = 37

Explanation:

In order to solve this equation, add 25 to both sides:

`\sf{-25+n=12}`

`\sf{n=12+25}`

`\sf{n=37}`

Therefore, n = 37.

Answer 2

`- 25 + n = 12`

`\Leftrightarrow - 25 + 25 + n = 12 + 25`

`\Leftrightarrow \: n = 37`
