\dfrac{k}{2}+1-1k=-2k\qquad\text{add 1k to both sides}\\\\\dfrac{k}{2}+1=-1k\qquad\text{multiply both sides by 2}\\\\\not2^1\cdot\dfrac{k}{\not2_1}+2\cdot1=2\cdot(-1k)\\\\k+2=-2k\qquad\text{subtract k from both sides}\\\\2=-3k\qquad\text{divide both sides by (-3)}\\\\\dfrac{2}{-3}=k\to k=-\dfrac{2}{3}

3(x + 1) - 2x = -6 what is X i need halp
Mashutka [201]

Answer:x=−9

Step-by-step explanation:

Apply the distributive property.

3 x + 3 ⋅ 1 − 2 x = − 6

Multiply  3  by  1

.

3 x + 3 − 2 x = − 6

Subtract 2x from 3x.

x + 3 = − 6

Move all terms not containing  x  to the right side of the equation.

Subtract 3 from both sides of the equation.

x = − 6 − 3

Subtract 3 from − 6 .

x = − 9
