  131 . x - 941 =16

  12 ( x - 1 ) : 3 = 103

Answer 1

Ta có \(131x-941=16\)

\(\Rightarrow131x=957\)

\(\Rightarrow x=\frac{957}{131}\)

b.\(12.\left(x-1\right):3=103\)

\(\Rightarrow12.\left(x-1\right)=309\)

\(\Rightarrow x-1=\frac{103}{4}\)

\(\Rightarrow x=\frac{107}{4}\)

Answer 2

Answer 3

131 . x -941 =  16

131.x = 16+941

131.x =957

x=957:131

x=957/131

12 (x-1) :3 =103

12 (x - 1 )=103 . 3

12 (x -1 ) = 309

x-1=309:12

x-1 = 25,75

x= 25,75+1

x=26,75
