\(x\) - (10 - \(x\)) = \(x\) - 22

\(x\) - 10 + \(x\) = \(x\) - 22

2\(x\) - 10 = \(x\) - 22

2\(x\) - \(x\)  = -22 + 10

\(x\)         = - 12

Dạ,em cảm ơn cô ạ!

\(-35-2x=-19\\\Rightarrow2x=-35-(-19)\\\Rightarrow2x=-35+19\\\Rightarrow2x=-16\\\Rightarrow x=-16:2\\\Rightarrow x=-8\\Vậy:x=-8.\)

−35−2x=−19

⇒2x=−35−(−19)

⇒2x=−35+19

⇒2x=−16

⇒x=−16:2

⇒x=−8

Vậy:x=−8.

là thứ cái đầu bạn ý hỏi thế cũng hỏi

chịu rồi

\(3x+60=-120\)

\(3x=-120-60\)

\(3x=-180\)

\(x=-180\div3\)

\(x=-60\)

\(3x+60=-120\\ \Rightarrow3x=-180\\ \Rightarrow x=-60.\) 

Vậy ....

`#3107.101107`

`(2x + 1)^3 = 343`

`\Rightarrow (2x + 1)^3 = 7^3`

`\Rightarrow 2x + 1 = 7`

`\Rightarrow 2x = 6`

`\Rightarrow x = 3`

Vậy, `x = 3.`

x=3

Bài khó lắmmm tr oiii

B = \(\dfrac{4}{7}\) = \(\dfrac{4.4}{7.4}\) = \(\dfrac{16}{28}\); I = \(\dfrac{6}{13}\) = \(\dfrac{6.\left(-2\right)}{13.\left(-2\right)}\) = \(\dfrac{-12}{-26}\)
