Question

128-3.(x+4)=23

Answer 1

          128 - 3(x + 4) = 23

\(\Leftrightarrow\)3(x + 4) = 128 - 23 = 105

\(\Leftrightarrow\)x + 4 = 105 : 3 = 35

\(\Leftrightarrow\)x = 35 - 4 = 31

Vậy x = 31

Answer 2

128-3.(x+4)=23

3.(x+4)=128-23

3.(x+4)=105

x+4=105:3

x+4=35

x=35-4

x=31

Answer 3

128-3.(x+4)=23

3.(x+4)=128-23

3.(x+4)=105

x+4=105:3

x+4=35

x=35-4

x=31

OK k mk nha 

Answer 4

128-3.(x+4)=23

=>3.(x+4)=128-24

=>3.(x+4)=105

=>x+4=105:3

=>x+4=35

=>x=35-4

=>x=31

 Vậy x=31

Answer 5

\(128-3.\left(x+4\right)=23\)

=> \(3.\left(x+4\right)=128-23=105\)

=> \(x+4=105:3\)

<=> \(x+4=35\)

=> \(x=35-4=31\)
