Question

x - 0.1x = 54solve for x

Answer 1

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:

$\begin{gathered} \frac{0.9x}{0.9}=\frac{54}{0.9} \\ x=60 \end{gathered}$

The answer is

$x=60$
