Question

How do you solve `-1= m - -10`?

Answer 1

m = -11

Explanation:

First it is necessary to simply `- - 10`

`+ xx +` = + ( If you add something good to something good it gets better good is positive adding is positive.

`- xx -` = + ( if you take away something bad it is good. take away is negative, bad is negative. so taking away something bad is good. good is positive.

Applying the principle that a negative times a negative is a positive.

`-1 = m - (-10)`

`-1 = m + 10`

Now subtract 10 from both sides.

`- 1 - 10 = m + 10 -10` This results in

`-11 = m`

Answer 2

`m = -11`

Explanation:

`-1 = m - -10`

The equation is not well written in this form. Better would be:

`-1 = m - (-10)" "larr` remove the bracket

`-1 = m+10" "larr` subtract 10 from each side

`-1-10 = m+10-10" "larr` simplify both sides

`-11 = m`
