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

What is.. 4x-2=(x+3)+2
Contact [7]

Answer:

x = 7/3

Step-by-step explanation:

4x - 2 = x + 3 + 2

4x - 2 = x + 5

Rearranging the terms, we get,

4x - x = 5 + 2

3x = 7

x = 7/3

Hence, x = 7/3.

Helpppp pleaseeee I need it tonight
snow_tiger [21]
What you want to first is substitute the numbers in for the variables in the equation

Since b= -5 , we will plug it in for -b

-5 + c = -13x

Now plug in -8 for c

-5 + (-8) = -13x

Add the numbers on the left side, which gives you -13.

-13 = -13x

Lastly, divide both sides by -13x, which will give you 1.

So x = 1
