Answer:
1. 4 or -4
2. 2 or -2
3. 5 or -1
4. 2
5. -2
6. 1 or 2
Step-by-step explanation:
Absolute values make the answer a positive value. So in the first one to make |x|=4, x can be either 4 or -4 because the lines around x tell you to remove the negative sign. Does this make sense? So for the answers, find the values for x that make the answer the value wanted, and then find the negative of the value wanted. For example, in |5x|=10, 5(2)=10 and 5(-2)=-10. But with absolute value signs, it changes it from -10 to 10. Hope this helps, if you have any questions please let me know.

Step-by-step explanation:
Answer:
Coal is formed of carbon.
Simplify 3/2t to 3t/2
16 - 2t = 3t/2 + 9
Multiply both sides by 2
32 - 4t = 3t + 18
Add 4t to both sideds
32 = 3t + 18 + 4t
Simplify 3t + 18 + 4t to 7t + 18
32 = 7t + 18
Subtract 18 from both sides
32 - 18 = 7t
Simplify 32 - 18 to 14
14 = 7t
Divide both sides by 7
14/7 = t
Simplify 14/7 to 2
2 = t
Switch sides
<u>t = 2</u>
