Answer 1

a)

$|2x + 3| - 4 \times |2 - 2x - 5) | = - 27 \\ = |2x + 3| - 4 \times | - 3x - 2x| = - 27 \\ = |2x + 3| - 4 \times | - (2x - 3)| = - 27 \\ = |2x + 3| - 4 \times |2x + 3| = - 27 \\ = - 3 \times |2x + 3| = - 27 \\ = |2x + 3| = + - 9 \\ \\ = solutia 1. |2x + 3| = 9 \\ = x = 3\\ = solutia2. |2x + 3| = - 9 \\ = x = - 6$
