Step-by-step explanation:

its hard to determine without the known value of x, but the above would be the equation needed to solve it if you knew what x was
Answer:
See below
Step-by-step explanation:
What we can do is try it out.
20*0.6=12
since 0.6 is left
now we increase 12 by 40, or multiply it by 1.4
12*1.4= 16.8
See what is happening here is that at first when we are decreasing it by 40 percent, we are taking 40 percent of 20. However, when we increase that amount by 40 percent, we are now increasing 40 percent of 20 by 40 percent, or increasing 16 by 40 percent. Therefore, we will not get the original amount.
