Question

75-7.(x-8)=12

Answer 1

\(\Rightarrow7\left(x-8\right)=63\\ \Rightarrow x-8=9\\ \Rightarrow x=17\)

Answer 2

    75 - 7.(x- 8) = 12

⇒ 7. (x - 8)       = 63

⇒        x- 8        = 9

⇒         x            = 17

Vậy x = 17

Answer 3

\(75 - 7 . (x - 8) = 12\)

\(7 . (x - 8) = 75 - 12\)

\(7 . (x - 8) = 63\)

\(x - 8 = 63 : 7\)

\(x - 8 = 9\)

\(x = 9 + 8\)

\(x = 17\)

Answer 4

75 - 7.(x - 8) = 12

       7.(x - 8) = 75 - 12

       7.(x - 8) = 63

          (x - 8) = 63 : 7

          (x - 8) = 9

                  x = 9 - 8

                  x = 1

Answer 5

⇒ 7 ( x − 8 ) = 63

⇒ x − 8 = 9

⇒ x = 17
