Answer:
x = 6
Step-by-step explanation:
3 - 2x + 6 = 2x - 9 - 6
- 2x - 2x = - 9 - 6 - 3 - 6
- 4x = - 24
- x = - 24/4
- x = - 6
x = 6

Answer:
x=20
Step-by-step explanation:
3x - 10 + 5x + 30 = 180
8x + 20 = 180
8x = 160
x = 160/8
x = 20
check:
3(20) - 10 + 5(20) + 30 = 180
60 - 10 + 100 + 30 = 180
50 + 100 + 30 = 180
150 + 30 = 180
180 = 180 ✓
1. True: the absolute value works exactly in this way: it turns negative numbers into their positive counterpart (e.g.: |-3|=3), and it does nothing on positive numbers (e.g.: |10|=10). So, the absolute value of a negative number will always be a positive number.
2. True (see above)
3. False: for example, you can pick -100 and 30. Their absolute value is 100 and 30, and 100>30. So, the absolute value of a negative number is greater the absolute value of a positive number.
