-4 - 8 - 8a <= -76 or -4 - 8 - 8a >= 76
-12 +8a <= -76 or -12 +8a >= 76
8a <= -64 or 8a >= 88
a <= -8 or a >= 11
Therefore the solution to -4 - | 8 - 8a| >= 76 consists of two intervals
a <= -8 and a >= 11

solve each inequality and graph its solution
-4 - | 8 - 8a| >= 76




 ----- Adding 4 to both sides

As seen,  exists since the left-side of inequality will ALWAYS YIELD a value that's < 0 (negative)
