Answer: 5

Step-by-step explanation:

x+3x−2=18

x+3x+−2=18

(x+3x)+(−2)=18(Combine Like Terms)

4x+−2=18

4x−2=18

Step 2: Add 2 to both sides.

4x−2+2=18+2

4x=20

Step 3: Divide both sides by 4.

x=5

Leto [7]

Step-by-step explanation:

$k + \frac{8}{3} = - 2$

$\frac{3k + 8}{3} = - 2$

Cross Multiplying

$3k + 8 = - 6$

$3k = - 6 - 8$

$3k = 14$

Therefore

$k = \frac{14}{3}$
