`a)` `3/2 x - 7/3 = (-1)/4`
`3/2 x = (-1)/4 + 7/3 = 25/12`
`x=25/12 : 3/2`
Vậy `x=25/18`
`b)` `3/4 + 2/5 x = 29/60`
`2/5 x = 29/60 - 3/4 = (-4)/15`
`x=(-4)/15 : 2/5`
Vậy `x=(-2)/3`
`c)` `3/5 - 1/2 x = 7/10`
`1/2 x = 3/5 - 7/10 = (-1)/10`
`x=(-1)/10 : 1/2`
Vậy `x=(-1)/5`
`d)` `x - 3/(4^2) = 1/16`
`x- 3/16 = 1/16`
`x=1/16 + 3/16`
Vậy `x=1/4`
