-4k+2(5k-6)=-3k-39

- 4 k + 2 (5 k - 6) = - 3 k - 39

k = - 3

Solution steps

- 4 k + 2 (5 k - 6) = - 3 k - 39

Expand

2 (5 k - 6) : 10 k - 12

- 4 k + 10 k - 12 = - 3 k - 39

Add similar elements:

- 4 k + 10 k = 6 k

6 k - 12 = - 3 k - 39

Move

12

to the right side

6 k = - 3 k - 27

Move

3 k

to the left side

9 k = - 27

Divide both sides by

9

k = - 3

5 = - x^{2} + 10 x - 21

r^{2} + 2 r - 8 = 0

- 5 x < 25

2 0^{- 8} \cdot 2 0^{8}

x^{2} - 21 = 4 x
