Solve the equation $\frac{n}{10} + 7 = 10$ for $n$ .

STEP 1

Assumptions
1. The equation to solve is $\frac{n}{10} + 7 = 10$ .
2. We need to isolate the variable $n$ to find its value.

STEP 2

First, we need to get rid of the constant term on the left side of the equation to isolate the term with the variable $n$ . We do this by subtracting 7 from both sides of the equation.
$\frac{n}{10} + 7 - 7 = 10 - 7$

STEP 3

Simplify both sides of the equation.
$\frac{n}{10} = 3$

STEP 4

Now, we need to isolate $n$ by getting rid of the fraction. We do this by multiplying both sides of the equation by 10.
$10 \times \frac{n}{10} = 3 \times 10$

STEP 5

Simplify both sides of the equation.
$n = 30$
The solution to the equation $\frac{n}{10} + 7 = 10$ is $n = 30$ .
