Question

5x -(3+4x) = 5. tìm x

 

Answer 1

5x - (3 + 4x) = 5

5x - 3 - 4x = 5

x - 3 = 5

x = 5 + 3

x = 8

Answer 2

\(5x-\left(3+4x\right)=5\)

      \(5x-3-4x=5\)

               \(5x-4x=5+3\)

                 \(=>x=8\)

Vậy \(x=8\)

Answer 3

\(5x-\left(3+4x\right)=5\)

     \(5x-3-4x=5\)

               \(5x-4x=5+3\)

                        \(\Rightarrow x=8\)
