need help with steps in solving, x+14=9+6x?

x+14 = 9+6x 
Subtract x on both sides of the equation 
x+14 (-x) = 9+6x (-x)
Simplifying we get:
14 = 9 + 5x
Subtract 9 on both sides of the equation 
14 (-9) = 9 + 5x (-9)
Simplifying we get:
5 = 5x
Divide both sides by 5 
5/5 = 5x/5
Simplifying we get 
1 = x
Rearranging we get 
x = 1

x + 14 = 9 + 6x

Step 1: Subtract 14 and 6x on each side.
x + 14 - 14 - 6x = 9 + 6x - 14 - 6x

Step 2: Calculate on each side.
-5x = -5

Step 3: Divided by -5 on each side.
-5x/(-5) = -5/(-5)

Step 4: Calculate on each side.
x = 1

how do you check the solution for 3x+15=4x+12, which the solution is-3

Deduct x from both sides and deduct 9 from both sides.
So: 5 = 5x 
Divide both sides by 5 and so x = 1

x+14=9+6x
x - 6x = 9 - 14
- 5x = -5
 x = 1 answer//

x + 14 = 9 + 6x
x = 1
