Question

375 : ( 45 - 4x ) = 15

Answer 1

\(45-4x=375:15\\ 45-4x=25\\ 4x=45-25\\ 4x=20\\ x=20:4\\ x=5\)

Answer 2

\(375:\left(45-4x\right)=15\)
\(45-4x=375:15\)
\(45-4x=25\)
\(4x=45-25\)
\(4x=20\)
\(x=20:4\)
\(x=5\)

Answer 3

\(375:\left(45-4x\right)=15\)

          \(45-4x=25\)

                  \(4x=20\)

                    \(x=5\)

Answer 4

375 : (45 - 4x) = 15

45 - 4x = 375:15

45- 4x = 25

      4x= 45 - 25

     4x = 20

      x = 5

Vậy x= 5
