Answer:

2,-12

Explanation:

The given equation is ,


\implies |x + 5 | = -7

We know that modulus only gives positive value , Therefore on squaring both sides we have ,


\implies (x + 5 )^2=( -7)^2 \\\\\implies (x+5)^2=7^2\\\\\implies x + 5 =\pm 7 \\\\\implies x = 7-5,-7-5 \\\\\implies \boxed{ x = 2, -12}
