To solve for x, we need to get rid of the -9 on the left side of the equation. We can do this by adding 9 to both sides.
So, 2x - 9 + 9 = 19 + 9
This simplifies to 2x = 28.
Next, we want to get x by itself. To do this, we can divide both sides of the equation by 2.
So, 2x/2 = 28/2
This simplifies to x = 14.
Therefore, the solution is x = 14.

Show the work to check that your answer is correct.
To check if the solution x = 14 is correct, we substitute the value of x back into the original equation and see if both sides are equal.
Original equation: 2x - 9 = 19
Substituting x = 14, we have:
2(14) - 9 = 19
Simplifying the left side of the equation, we get:
28 - 9 = 19
Finally, we evaluate the equation:
19 = 19
Since both sides of the equation are equal, we can conclude that x = 14 is indeed the correct solution.
