Question

-2/3z= 4 find the value of z in the following and verify it​

Answer 1

Answer:

finding the solution:--

-2/3z = 4

-2 = 4 × 3z

-2 = 12z

z = -2/12

z= -0.1666(approx.)

verification :---

as z= -0.1666 is a approx value, we will take

z =-2/12 for accurate answer

-2/(3× -2/12) = 4

-2/(-1/2)= 4

-2 = 4 × -1/2

-2 = -2

Answer 2

Answer:

z = -1/6

Step-by-step explanation:

-2/3z=4

-2 = 4(3z)

-2 = 12z

-2/12 = z

-1/6 = z

verification:

-2÷3(z) = 4

=> -2÷3(-1/6) = 4

=> -2÷(-1/2) = 4

=> -2*-2 = 4
