Answer:
Step-by-step explanation:
I take it that this is some sort of ratio. Start by solving the brackets on the left.
Brackets: 1/3 - 1/10
Brackets: 10/30 - 3/30
Brackets: 7/30
Brackets^2: 49/900
Brackets^2 - 1/5: 49/900 - 180/900
Brackets^2 - 1/5: -131/900
(2/5)^2 = 4/25
The way this read, it should be
![\frac{\frac{-131}{900} }{\frac{4}{25} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B-131%7D%7B900%7D%20%7D%7B%5Cfrac%7B4%7D%7B25%7D%20%7D)
Which when you invert and multiply becomes
![\frac{-131}{900} * \frac{25}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-131%7D%7B900%7D%20%2A%20%5Cfrac%7B25%7D%7B4%7D)
which finally becomes
![\frac{-131}{144}](https://tex.z-dn.net/?f=%5Cfrac%7B-131%7D%7B144%7D)
Answer:
x=0
Step-by-step explanation:
Subtract 1 from both sides
2x+1-1<1-1
Simplify the arithmetic
2x<1-1
Simplify the arithmetic
2x<0
Isolate the X
X=0
