Question

720 : [ 41 - (2x - 5 )=40

Answer 1

\(720\div[41-\left(2x-5\right)]=40\)

\(720\div\left(41-2x-5\right)=40\)

\(36-2x=720\div40\)

\(36-2x=18\)

\(2x=18\)

\(x=9\)

Answer 2

\(720:\left[41-\left(2x-5\right)\right]=40\)

\(\Leftrightarrow41-\left(2x-5\right)=720:40\)

\(\Leftrightarrow41-2x+5=18\)

\(\Rightarrow46-2x=18\)

\(\Leftrightarrow2x=28\)

\(\Leftrightarrow x=14\)

Answer 3

720:[41 -(2x-5) =40

        41 -(2x-5)=720:40

        41 -(2x-5)= 18

               2x-5 =41-18

               2x-5=23

               2x   =23+5

               2x   =28

                 x    =28:2

                 x   =14
