Question

25. Solve : 3(5z - 7) - 209z - 11) = 4(8z – 13) - 17​

Answer 1

Answer:

here's ur answer

Step-by-step explanation:

3 ( 5z - 7 ) - 209z - 11 = 4 ( 8z - 13 ) - 17

15z - 35 - 209z - 11 = 32z - 52 - 17

- 194z - 32z = - 69z + 46

226z = 23

z = 0.101

Answer 2

The correct answer is "z = 0.101". Further explanation is given below.

Step-by-step explanation:

The given equation is:

3(5z-7)-209z-11 = 4(8z-13)-17​

On solving the above equation, we get

⇒  15z-35-209z-11 = 32z-52-17

⇒  -194z-46 = 32z-69

⇒  -194z-32z = -69+46

⇒  -226z = -23

⇒  z = $\frac{-23}{-226}$

⇒  z = 0.101
