Question

Decide whether the given number is a solution of the given equation.

Is - 7 a solution of x + 12 = 19?

Answer 1

`x=7`

-7 is not a solution for
`x+12=19`

Explanation:

`x +12 = 19`

Subtract 12 from both sides

`x = 19-12`

Subtract 12 from 19 to get 7

`x = 7`

It would be -7 if it was
`-x+12=19`

Answer 2

No

Step-by-step explanation:

-7+12=5
