Answer 3

Ta có: \(315+\left(146-x\right)=401\)

\(\Rightarrow146-x=401-315\)

\(\Rightarrow-x=401-315-146\)

\(\Rightarrow-x=-60\)

\(\Rightarrow x=60\)

Vậy \(x=60\)

Answer 4

Ta có :

315 + ( 146 - x ) = 401

146 - x = 401 - 315

146 - x = 86

x = 146 - 86

x = 60

Vậy x = 60

Answer 5

\(a,315+\left(146-x\right)=401\\ 146-x=401-315\\ 146-x=86\\ x=146-86\\ x=60\)

Answer 6

a) Ta có: \(315+\left(146-x\right)=401\)

\(\Leftrightarrow315+164-x=401\)

\(\Rightarrow-x=401-315-164\)

\(\Rightarrow-x=-68\)

\(\Rightarrow x=68\)

Vậy \(x=68\)
