Question

(2z-7)-3(3z+8)=4z-9​

Answer 1

Solution :

(2z-7)-3(3z+8)=4z-9

=> 2z-7-9z-24=4z-9

=> -7z-4z=9-31

=> -11z= -22

=> z = 22/11

=> z = 2 ( answer )

Answer 2

Step-by-step explanation:

$(2z - 7) - 3(3z + 8) = 4z - 9 \\ \\ (2z - 7) - 9z - 24 = 4z - 9 \\ \\ 2z - 7 - 9z - 24 = 4z - 9 \\ \\ - 31 - 7z = 4z - 9 \\ \\ - 31 + 9 = 7z - 4z \\ \\ - 22 = 3z \\ \\ z = \frac{ - 22}{3}$
