Answer: D) 18

Step-by-step explanation:

6 - x = -12

Subtract 6 from both sides.

-x = -18

Divide by -1 on both sides so as to isolate x.

x = 18

Answer:

D. 18

Step-by-step explanation:

The first thing you need to do is subtract 6 from both sides. This makes it cancel out on the left, since 6 - 6 = 0, and subtract 6 from -12:

6 − x = −12

-6        - 6

________

-x = -18

Then divide both sides by -1, because there's a negative sign (-) in front of the x, meaning there's like an invisible 1 there:

-1x = -18

x = 18

6 (x-6) = -3 (-x + 3)
Bond [772]
You have to distribute!
6(x) = 6x and 6(-6)=-36
So now you have 6x-36=-3(-x+3)
Now do the same on the other side.
-3(-x)=3x -3(3)=-9
So now, 6x-36=3x-9
Combine the like terms:
Subtract 3x in both sides.
6x-3x=3x
Now: 3x-36=-9
Add 36 in both sides.
3x=27
Divide by 3 on both sides to get x alone.
3x/3= x 27/3=9
X=9
