k/2+1-1k=-2k

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

k = - \frac{2}{3}

Solution steps

\frac{k}{2} + 1 - 1 \cdot k = - 2 k

Multiply:

1 \cdot k = k

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

Move

1

to the right side

\frac{k}{2} - k = - 2 k - 1

Multiply both sides by

2

- k = - 4 k - 2

Move

4 k

to the left side

3 k = - 2

Divide both sides by

3

k = - \frac{2}{3}

6 x^{2} + 27 x - 15

a^{4} - 4 b^{4}

7 x^{2} + 5 - x = 6 x^{2} + 10

e^{x} > 7

u^{4} - 11 u^{3} + 10 u^{2}
