6x + 3 = 3x - 12
6x + 3 - 3x = 3x - 12 - 3x
3x + 3 = - 12
3x + 3 - 3 = - 12 - 3
3x = - 15
3x / 3 = 15 / 3
x = 15 / 3
x = 5

6x+3=3x-12
isolate the x to one side of the equation by subtracting 3x from both sides
6x-3x+3=-12
combine like terms
3x+3=-12
subtract 3 to get the 3x by itself
3x=-12-3
combine like terms
3x=-15
divide both sides by 3
x=-5

Well, take 3 from -12, which is -15.
Then take 3x from 6x, which is 3x.
Divide 3x by -15 and see what you get.

6x + 3 = 3x - 12
1st> Subtract 3x from both sides of =
6x - 3x + 3 = 3x -12 - 3x
which becomes: 3x + 3 = -12
2nd> Subtract 3 from both sides of =
3x +3 - 3 = -12 - 3
which becomes: 3x = -15
3rd> Divide both sides by 3 to get x by itself:
3/3 * x = -15 / 3
which becomes 1 * x = -5 or x = -5.

6x + 3 = 3x - 12
6x - 3x = -12 - 3
3x = -15
x = -15 / 3
x = -5
Proof:
(6 * [-5]) + 3 = (3 * [-5]) - 12
-30 + 3 = -15 -12
-27 = - 27

Subtract 3x from both sides to get
3x+3=-12
Subtract 3 from both sides to get
3x=-15
Divide -15 by 3
x=-15/3 = -5
x=-5

Step 1. subtract 3x from 6x and subtract 3 from -12.
6x+3=3x-12
6x = -12
-3x -3
U will get....
3x = -15
Step 2. divide 3 from both sides
3x = -15
__ __
3 3
u will be left with
x = - 5

6x+3=3x-12
6x-3x+3 = -12
3x + 3 = -12
3x +3 -3 = -12 - 3
3x = -15
3x/3 = -15/3
x = -5

Hey there!
Here's the answer.
6x+3=3x-12 -->
6x-3x+3=3x-3x-12 -->
3x+3=-12 -->
3x+3-3=-12-3 -->
3x=-15 -->
x=-5
The solution is x=-5.
I hope it helps!
