Z-7/3-z-5/12=2z-27/15

Answer»

Answer:

=> Z = - 19/ 40 is the answer.

Step-by-step explanation:

Z-7/3-z-5/12=2z-27/15

=> z - z -7/3 -5/12 = 2z -27/15

=> (z - z) + (-7/3 -5/12) = 2z -27/15

=> 0 - (7/3 + 5/12) +27/15 = 2z

=> - [(7x 4)/(3X4) + 5/12) +27/15 = 2z

=> - [28/12 + 5/12) +27/15 = 2z

=> - [(28+5)/12) +27/15 = 2z

=> - 33/12 +27/15 = 2z

=> 2z = - 33/12 + 27 /15

=> 2z = - (33 x 5)/(12x 5) + (27 x 4)/ (15 x 4)

=> 2z = - 165/60 + 108/ 60

=> 2z = (- 165+ 108)/ 60

=> 2z = - 57/ 60

=> z = - 57/ (60 x 2)

=> z = - 57/ 120

=> z = - 19/ 40
