    No because if you substitute m for - 2, you'll see that - 2 plus 3 equals 1, not 5.

    We can apply - 2 inside the equation.

    m+3=-5

    -2+3=-5

    This is incorrect because - 2+3 is not equal to - 5, it is equal to 1.

    Lets find the correct value for m

    m+3=-5

    -3 - 3

    m=-8

    So the value that would make our equation true is m=-8

    Because ...

    -8+3=5
