2k+3(k-1)=17

2 k + 3 (k - 1) = 17

k = 4

Solution steps

2 k + 3 (k - 1) = 17

Expand

3 (k - 1) : 3 k - 3

2 k + 3 k - 3 = 17

Add similar elements:

2 k + 3 k = 5 k

5 k - 3 = 17

Move

3

to the right side

5 k = 20

Divide both sides by

5

k = 4

- (x + 1) (x + 2) (x + 3) < 0

e^{- 0.2}

2 (x - 4) = 6 x

6 (y + 3) = 30

\frac{( 1 + i ) ( 1 - 2 i )}{3 + i}
