(exact form)   z= -7/5

or

(decimal form)   z= -1.4

or

(mixed number form)   z= -12/5

Step-by-step explanation:

The value of z is -7/5

Step-by-step explanation:

1/3 (z + 1/5) = -2/5

z/3 + 1/5 × 3 = -2/5

z/3 + 1/15 = -2/5

15z + 3/45 = -2/5

15z + 3 = -2(45) ÷ 5

15z + 3 = -2(9)

15z + 3 = -18

15z = -18 – 3

15z = -21

z = -21/15

z = -7/5

Thus, The value of z is -7/5
