Question

Answer 1

`x/8 = 6/(-24)`

`x/8 = (-6)/24`

`x/8 = -1/4`

`x=(-1/4) . 8`

`x=-2`

______________________

`x : 6 = 4/27`

`x=4/27 . 6`

`x=8/9`

_______________

`5/24 + x  =7/12`

`x=7/12 -5/24`

`x=14/24 - 5/24`

`x=3/8`

____________________________

\(\left(x+\dfrac{1}{2^2}\right)-0,75=5\%\)

\(\left(x+\dfrac{1}{4}\right)-\dfrac{3}{4}=\dfrac{1}{20}\)

`x+1/4 = 1/20 - 3/4`

`x+1/4 = 1/20 - 15/20`

`x+1/4 = -7/10`

`x=-7/10 + 1/4`

`x=-9/10`

_________________________________

\(\dfrac{2x+3}{-4}=\dfrac{3-x}{7}\)

`7.(2x+3)=-4.(3-x)`

`14x + 21 = 4x - 12`

`14x - 4x = 12 + 21`

`14x - 4x = 33`

`(14-4)x = 33`

`10x = 33`

`x=33:10`

`x=33/10`
