Answer 5

96 - 3 ( x + 1 ) = 42

       3 ( x + 1 ) = 54

            x + 1   = 18

                  x   = 17

12x - 30 = 3 ² x 3 ³

12x - 30 = 243

12x        = 273

    x        = 22,75

Answer 6

96-3(x+1)=42

12x-30=3²x3³

96 - 3 ( x + 1 ) = 42

       3 ( x + 1 ) = 54

            x + 1   = 18

                  x   = 17

12x - 30 = 3 ² x 3 ³

12x - 30 = 243

12x        = 273

    x        = 22,75

Answer 7

96 - 3 ( x + 1 ) = 42

      3 ( x + 1 ) = 96 - 42

      3 ( x + 1 ) = 54

             x + 1 = 54 : 3 

             x + 1 = 18

                   x = 18 - 1 

                   x = 17

12 x - 30 = 3 x 3 x 3 x 3 x 3

12 x - 30 = 243

      12 x = 243 + 30

      12 x =273

          x = 273 : 12

          x = 22,75
