Question

Find the value of n that makes the equation -2=n+10 true.

Answer 1

Given:

`-2=n+10`

To solve, we need to get n isolated on one side. To do this, subtract 10 from both sides. This will cancel the +10 on the right side and give us -12 of the left, leaving us with:

`-12=n` or
`n=-12`

If you want to check your answer, plug in -12 for n.

`-2=-12+10`

`-2=-2`

The statement is true, therefore,
`n=-12`.

Answer 2

subtract 10 on both sides to isolate the variable (n).

-2 = n + 10

-10 -2 = n + 10 -10

-12 = n + 0

-12 = n

Answer: -12
