Toán 5/6 -( 1/2 + x ) = 1/5 – 2 X + ( 1/3 – 1/5 ) 14/07/2021 By Brielle 5/6 -( 1/2 + x ) = 1/5 – 2 X + ( 1/3 – 1/5 )
Đáp án + Giải thích các bước giải: `5/6 -( 1/2 + x ) = 1/5 – 2x + ( 1/3 – 1/5 )` `=> 5/6 – 1/2 – x = 1/5 + 1/3 -1/5 – 2x` `=> 1/3 – x = 1/3 – 2x` `=> -x + 2x = 1/3 – 1/3` `=> x = 0` Vậy `x=0` Trả lời
Đáp án: `5/6 – (1/2 + x) = 1/5 – 2x + (1/3 – 1/5)` `-> 5/6 – 1/2 – x = 1/5 – 2x + 2/15` `-> (5/6 – 1/2) – x = (1/5 + 2/15) – 2x` `-> 1/3 – x = 1/3 – 2x` `-> 1/3 – 1/3 = x – 2x` `-> -x = 0` `-> x = 0` Vậy `x = 0` Trả lời
Đáp án + Giải thích các bước giải:
`5/6 -( 1/2 + x ) = 1/5 – 2x + ( 1/3 – 1/5 )`
`=> 5/6 – 1/2 – x = 1/5 + 1/3 -1/5 – 2x`
`=> 1/3 – x = 1/3 – 2x`
`=> -x + 2x = 1/3 – 1/3`
`=> x = 0`
Vậy `x=0`
Đáp án:
`5/6 – (1/2 + x) = 1/5 – 2x + (1/3 – 1/5)`
`-> 5/6 – 1/2 – x = 1/5 – 2x + 2/15`
`-> (5/6 – 1/2) – x = (1/5 + 2/15) – 2x`
`-> 1/3 – x = 1/3 – 2x`
`-> 1/3 – 1/3 = x – 2x`
`-> -x = 0`
`-> x = 0`
Vậy `x = 0`
