Answer:
[tex]x \geqslant 4 \: or \: x \leqslant - 12[/tex]
Step-by-step explanation:
The given absolute value inequality is:
[tex]5 - |x + 4| \leqslant - 3[/tex]
Let us subtract 5 from both sides to get:
[tex] - |x + 4| \leqslant - 3 - 5[/tex]
We simplify to get:
[tex] - |x + 4| \leqslant - 8[/tex]
We divide through by -1 to get:
[tex]|x + 4| \geqslant 8[/tex]
By the definition of absolute value function,
[tex](x + 4) \geqslant 8 \: or \: - (x + 4) \geqslant 8[/tex]
Divide through the second inequality by -1 and reverse the inequality sign.
[tex](x + 4) \geqslant 8 \: or \: (x + 4) \leqslant - 8[/tex]
Subtract 4 from both sides of both inequalities.
[tex]x \geqslant 8 - 4 \: or \: x \leqslant - 8 - 4[/tex]
[tex]x \geqslant 4 \: or \: x \leqslant - 12[/tex]
