Ответ:

To solve the equation 3x - 2x + x = 54, we can combine like terms on the left side of the equation:

2x + x = 54

Now, we can simplify the left side:

3x = 54

To isolate x, we can divide both sides of the equation by 3:

3x/3 = 54/3

This simplifies to:

x = 18

So, the solution to the equation is x = 18.
