Answer 1

`71- (33+x)=26`

`=> 33+x = 71-26 = 45`

`=> x =45 -33 = 12`

Vậy `x=12`

Answer 2

\(\Leftrightarrow-\left(33+x\right)=26-71\\ \Leftrightarrow-33-x=-45\\ \Leftrightarrow x=12\)

Answer 3

`=> 33 + x = 45`

`-> x = 12`.

Answer 4

\(71-\left(33+x\right)=26\)

\(\Rightarrow33+x=71-26\)

\(\Rightarrow33+x=45\)

\(\Rightarrow x=45-33\)

\(\Rightarrow x=12\)

Answer 5

\(\Rightarrow33+x=71-26\)

\(\Rightarrow33+x=45\)

\(\Rightarrow x=45-33\)
