Answer:
x=3.5
Step-by-step explanation:
add 2 to each side to cancel out the -2
6x=2x+14
subtract 2x from each side
4x=14
divide by 4
x=3.5
Lets pick a random number, like 50. Lets decrease and increase it by 50%. After the decrease, you will get 25, but when you increase it by 50%, it's only 37.5. No, because when you decrease it, you have a smaller base, so it increases less than it decreases. 50% of 100 is 50, but 50% of 50 is 25. You can see there is a significant difference.
