One minus two by three equals x minus one by two

One minus two by three equals x minus one by two

x=11／10

When x = 3, find the value of [x & # 178; - 2x / 1 minus X & # 178; - 4x + 4 / 1] / X & # 178; - 2x / 2

[1/(x²-2x)-1/(x²-4x+4)]÷2/(x²-2x)
=[1/x(x-2)-1/(x-2)²]*x(x-2)/2
=1/2-x/[2(x-2)]
=(x-2-x)/[2(x-2)]
=-1/(x-2)
=-1/(3-2)
=-1

The (2x + 2) of 2 minus the X of 2 is equal to 1. How much is x equal to

Let a = 2 ^ X
Then 2 ^ (2x + 2)
=2^2x*2²
=4a²
So 4A & # 178; - a = 1
4a²-a-1=0
a=(1±√17)/8
a=2^x>0
SO 2 ^ x = (- 1 + √ 17) / 8
x=log2[(-1+√17)/8]

How to do x minus 10 plus 30 equals 2x?
The original title is: when a bus arrives at station a, there are 10 people getting off the bus and 30 people getting on the bus. This is twice the number of people on the bus. How many people were on the bus

x-10+30＝2x
2x-x=30-10
x=20
