-2(z+3)-z=-z-4(z+2)<br> solve for z quickly please! will give brainliest

anyanavicka [17]

Answer:

$\sf z = - \dfrac{2}{3}$

Step-by-step explanation:

Solve for z:

$\longrightarrow$ -2(z + 3) = -z - 4(z + 2)

-4(z + 2) = -4z - 8:

$\longrightarrow$ -2(z + 3) = -z -4z - 8

Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:

$\longrightarrow$ -2(z + 3) = (-z - 4z) - 8

-z - 4z = -5z:

$\longrightarrow$ -2 (z + 3) = -5z - 8

Expand out terms of the left hand side:

$\longrightarrow$ -2z - 6 = -5 z - 8

Add 5z to both sides:

$\longrightarrow$ (5z - 2z) - 6 = (5z - 5z) - 8

5z - 5z = 0:

$\longrightarrow$ (5z - 2z) - 6 = -8

5z - 2z = 3z:

$\longrightarrow$ 3z - 6 = -8

Add 6 to both sides:

$\longrightarrow$ 3z + (6 - 6) = 6 - 8

6 - 6 = 0:

$\longrightarrow$ 3z = 6 - 8

6 - 8 = -2:

$\longrightarrow$ 3z = -2

Divide both sides of 3z = -2 by 3:

$\longrightarrow$ $\sf \dfrac{3}{3}z = - \dfrac{2}{3}$

$\sf \dfrac{3}{3} = 1 :$

$\longrightarrow$ $\sf z = - \dfrac{2}{3}$
