Answer: x = 60

Explanation:

To solve for x, we will isolate the variable with simplifying and reverse operations.

Given:

x - 0.1x = 54

Subtract 0.1 from 1:

0.9x = 54

Divide both sides of the equation by 0.9:

x = 60

The equation to solve:


x-0.1x=54

We can subtract the like terms on the left hand side:


\begin{gathered} (1-0.1)x=54 \\ 0.9x=54 \end{gathered}

Now, we can divide both sides by 0.9 and solve for x. Shown below:


\begin{gathered} (0.9x)/(0.9)=(54)/(0.9) \\ x=60 \end{gathered}

The answer is


x=60
