Keep going. Make a balanced move so that x is alone on the left, and then rewrite the equation to solve for the value of x.

To isolate \( x \) in the equation, you've started with:

\[ 50 + 5x = 60 \]

Next, you subtract 50 from both sides:

\[ 50 + 5x - 50 = 60 - 50 \]

This simplifies to:

\[ 5x = 10 \]

Now, to solve for \( x \), divide both sides by 5:

\[ x = \frac{10}{5} \]

So,

\[ x = 2 \]

Therefore, the value of \( x \) is 2.
