10-54.

Solve for all possible values for $x$ in each equation.

$– 2|x|=-8$
Hint (a):
Divide both sides by $-2$ to isolate the variable in the absolute value.

$| x - 3.2 | = 4.7$
Hint (b):
Either $x −3.2 = 4.7$ or $x −3.2 = -4.7$

$| 9 + 6 x | = 4$
Hint (c):
Either $9 + 6x = 4$ or $9 + 6x = -4$

$| - 7 x - 7 |= 1$
Answer (d):
$x=-\frac{8}{7} \text { or } x=-\frac{6}{7}$
