2/3x-1/5=x-1
Add similar elements 23x-15=8x
Subtract x from both sides 8x-x=x-1-x
Simply 7x=-x
Divide both sides by 7 7x = -1
__ __. *Simply: x=-1/7

Answer:
1110000
Step-by-step explanation:
1. We assume, that the number 3700000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 3700000 is 100%, so we can write it down as 3700000=100%.
4. We know, that x is 30% of the output value, so we can write it down as x=30%.
5. Now we have two simple equations:
1) 3700000=100%
2) x=30%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
3700000/x=100%/30%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 30% of 3700000
3700000/x=100/30
(3700000/x)*x=(100/30)*x - we multiply both sides of the equation by x
3700000=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x
3700000/3.33333333333=x
1110000=x
x=1110000
now we have:
30% of 3700000=1110000
