Question

Find k if 0.7k – 1.9 = 0.3 ( k + 14 )​

Answer 1

Answer:

k = 61/4 or 15.25

Step-by-step explanation:

0.7k – 1.9 = 0.3 ( k + 14 )

0.7k - 1.9 = 0.3k + 4.2

0.4k = 6.1

4k = 61 [Multiplying both sides by 10]

k = 61/4 or 15.25

Answer 2

Answer:

k = - 18

Step-by-step explanation:

0.7 - 1.9 = 0.3 (k + 14)

-1.2 = 0.3 (k + 14)

-1.2 = 0.3k + 4.2

-1.2 - 4.2 = 0.3k

-5.4 = 0.3k

-5.4/0.3 = k

k = - 18
