Đáp án+Giải thích các bước giải:
`a) -3/4 + x = 1/6`
`=> x = 1/6 +3/4`
`=> x = 11/12`
`b) 3/4 - x = 1/5`
`=> x = 3/4 - 1/5`
`=> x = 11/20`
`c) 3/5x - 1/4 = 1/10`
`=> 3/5x = 1/10 + 1/4`
`=> 3/5x = 7/20`
`=> x = 7/12`
`d) 1/3 + 2/3x = -4/9`
`=> 2/3x = -4/9 - 1/3`
`=> 2/3x = -7/9`
`=> x = -7/6`
`e) 5/4 - (1/6+x) = -1/5`
`=> 1/6+ x = 5/4 + 1/5`
`=> 1/6 + x = 29/20`
`=> x = 77/60`
