19х-х-14=256

To solve the equation, combine like terms on the left side of the equation:

19x - x - 14 = 256

Simplify:

18x - 14 = 256

Now, isolate the variable by adding 14 to both sides:

18x = 270

Finally, divide both sides of the equation by 18:

x = 15

So, the solution to the equation is x = 15.
