well you have to get x alone so in order to cancel out the 0.05 multiplication you have to do the opposite. In other words devide it by 0.05. (x times 0.05 devided by 0.05 = x so you are left with x on that side of the equal sign)
Then, to keep the sides equal, you have to do the same to 1. (x = 1/0.05)
First, you artwork out the equation for each: one million. you're taking the backside fee and then upload to it the cost situations the whole $ six hundred +.02x 1000 +.015x 2. Set the equations equivalent to a minimum of one yet another, because of the fact the question is for whilst the earning are equivalent six hundred +.02x = 1000 +.015x 3. Subtract six hundred to the remarkable area, and subtract the .015x to the left .005x=4 hundred 4. Divide 4 hundred via .0.5 to get your answer of $80,000

You could just divide both sides by 0.05, but it seems easier to get rid of the decimal fraction by first multiplying both sides by 100.
100(0.05)x = 100(1)
5x = 100. Now, isn't that nicer?
5x/5 = 100/5
x = 20
0.05x = 1
x= 1/0.05
x=1*100 / 0.05*100
=100/5
=20
0.05x = 1
x = 20.

1 devided by 0.05 is 20 so you are left with x=20
So what if the asvab test says
6: If 0.05 ÷ x = 1, then x =
A. 0.05
B. 0.5
C. 50
D. 5
Divide both sides by 0.05. You get x=20.

.05= 1/20
.05x= x/20=1, therefore, x=20.
