Sagot :

Answer:

x = 9

Step-by-step explanation:

23 = 7/9(6x - 36) + 9

23 = 7(6x - 36) / 9 + 9

23 = 7(6x - 36) / 9 + 9

-9                            -9

----------------------------------

14 =  7(6x - 36) / 9

*9                       *9

----------------------------------

126 = 7(6x - 36)

/7        /7

-----------------------------------

18 = 6x - 36

+36       +36

-----------------------------------

54 = 6x

/6     /6

9 = x

Answer:

x=9

Step-by-step explanation:

23 = 7/9(6x - 36) + 9

9(23) = 9(7(6x - 36)/9 + 9)

207 = 7(6x - 36) + 81

207 = (42x - 252) + 81

207 = 42x - 252 + 81

207 = 42x - 171

378 = 42x

9 = x

x = 9
