Answer:

<h2>z = 6</h2>

Step-by-step explanation:

4(z+1)=2(z-1)+18\qquad\text{use the distributive property}\\\\(4)(z)+(4)(1)=(2)(z)+(2)(-1)+18\\\\4z+4=2z-2+18\qquad\text{subtract 4 and}\ 2z\ \text{from both sides}\\\\4z-2z+4-4=2z-2z-2+18-4\qquad\text{combine like terms}\\\\2z=12\qquad\text{divide both sides by 2}\\\\z=6

4w+15= -13<br><br> -12=n/2-6
Firlakuza [10]

Answer:

For the one including 4w the answer is - 7

The one with n/2 is - 12

Step-by-step explanation:

4w=-13-15

4w=-28

w=-7

Multiply by 2 on both sides

-24=n-12

-24+12=n

Always write it in the variables perspective.

n=-12
