(-(2k-1))/4 = 2/5

\frac{- ( 2 k - 1 )}{4} = \frac{2}{5}

k = - \frac{3}{10}

Decimal Notation

k = - 0.3

Solution steps

\frac{- ( 2 k - 1 )}{4} = \frac{2}{5}

Multiply both sides by

4

- 2 k + 1 = \frac{8}{5}

Move

1

to the right side

- 2 k = \frac{3}{5}

Divide both sides by

- 2

k = - \frac{3}{10}

\frac{2}{3} x - \frac{1}{2} = - x + 2

5 (2 x + 3) - 7 x = 21

3 x + 9 = 10

(8 + x)^{2} - x (7 x - 1) = (x - 8)^{2} - 8 x - 7 (x + 3) (x - 3)

(2 x + 3) - (x + 4 - 2 x) = 5 - (x + 2)
