Question

Tìm x : 80:(3.x-4) = 16

Answer 1

80 : (3.x - 4) = 16

3x - 4 = 80 : 16

3x - 4 = 5

3x = 5 + 4

3x = 9

x = 9 : 3

x = 3

Answer 2

\(80:\left(3x-1\right)=16\)

\(\Rightarrow3x-4=80:16\)

\(\Rightarrow3x-4=5\)

\(\Rightarrow3x=5+4\)

\(\Rightarrow3x=9\)

\(\Rightarrow x=9:3\)

\(\Rightarrow x=3\)

Vậy \(x=3\)
