2k+3(k+4)=-3

2 k + 3 (k + 4) = - 3

k = - 3

Solution steps

2 k + 3 (k + 4) = - 3

Expand

3 (k + 4) : 3 k + 12

2 k + 3 k + 12 = - 3

Add similar elements:

2 k + 3 k = 5 k

5 k + 12 = - 3

Move

12

to the right side

5 k = - 15

Divide both sides by

5

k = - 3

\frac{7}{3} (6 x + 6) \leq 6 x - 6

(4 t - 6)^{2} - 12 (4 t - 6) + 20 = 0

(\frac{1}{2} + \frac{1}{3})^{2}

\frac{- x + 5}{x - 8} \geq 0

x^{3} - 6 x^{2} - x + 6 \geq 0
