Question

How do you solve `x + 13 = -8`?

Answer 1

`x = -21`

Explanation:

To solve for the variable `x`, we have to isolate it (make it by itself). To do so, subtract `color(blue)(13)` from both sides of the equation:
`x + 13 quadcolor(blue)(-quad13) = -8 quadcolor(blue)(-quad13)`

Therefore,
`x = -21`

Hope this helps!
