Question

(i) 3(2z - 3) = 12(2Z + 4)​

Answer 1

Answer:

Step-by-step explanation:

3(2z -3) = 12 (2z + 4)

6z - 9 = 24z + 48

6z - 24z = 48 + 9

-18z = 57

z = 57/-18

z = 19/-6

z= -19/6

Answer 2

Answer:

$3(2z - 3) = 12(2z + 4) \\ = > 6z - 9 = 24z + 48 \\ = > 6z - 24z = 48 + 9 \\ = > - 18z = 57 \\ = > z = \frac{57}{18} = 3.16$
