Answer:
1. x = {-3, 3}
2. a = {-12, -2}
3. v = {-7, 10}
4. m = {-8, 8}
5. k = {-11, 1}
6. y = {-13, 19}
Explanation:
|-2x| = 6
means that
-2x = 6 or -2x = -6
x = -3 or x = 3
|a + 7| = 5
means that
a + 7 = 5 or a + 7 = -5
a = -2 or a = -12
|8v-12| = 68
means that
8v-12 = 68 or 8v-12 = -68
8v = 80 or 8v = -56
v = 10 or v = -7
| m / -4 | + 1 = 3
| m / -4 | = 2
means that
m/-4 = 2 or m/-4 = -2
m = -8 or m = 8
3|k + 5| = 18
|k+5| = 6
means that
k + 5 = 6 or k + 5 = -6
k = 1 or k = -11
|2y - 6| / 4 = 8
|2y - 6| = 32
means that
2y - 6 = 32 or 2y - 6 = -32
y = 19 or m = -13
