Question

4.(x-3) = 7² - 1¹⁰

Answer 1

4.( x - 3 ) = 7² - 1¹⁰

4.( x - 3 ) = 49 - 10

4.( x - 3 ) = 39

   ( x - 3 ) = 39 : 4

   ( x - 3 ) = 9,75

     x       = 9,75 + 3

     x       = 12,75

Answer 2

4 . (x - 3) = 7² - 1¹⁰

4. (x - 3) = 49 - 1

4 . (x - 3) = 48

      x - 3  = 48 : 4

      x - 3  = 12

      x       = 12 + 3

      x       = 15
