Giúp em nha mn chiều đi rồi em cho 5sao

`a . `

`2x+1/2=-5/3`

`=>2x=(-5/3)-1/2`

`=>2x=(-10/6)-3/6`

`=>2x=-13/6`

`=>x=(-13/6):2`

`=>x=(-13/6) . 1/2`

`=>x=-13/12`

Vậy `x=-13/12`

`b . `

`1/7-3/5x=-0,6`

`=>1/7-3/5x=-3/5`

`=>3/5x=1/7-(-3/5)`

`=>3/5x=5/35-(-21/35)`

`=>3/5x=26/35`

`=>x=26/35:3/5`

`=>x=26/35 . 5/3`

`=>x=26/21`

Vậy `x=26/21`

$\\$

`e . `

`x^2=36`

`=>x=+-6`

Vậy `x=+-6`

$\\$

`f . `

`4x^2=144`

`=>x^2=144:4`

`=>x^2=36`

`=>x=+-6`
Vậy `x=+-6`
