Question

6. Put the steps in order to solve the equation:
3n + 9 + 4n = 2

Answer 1

To solve the equation \( 3n + 9 + 4n = 2 \), you can follow these ordered steps:

1. **Combine like terms on the left side.**
\[
3n + 4n + 9 = 2 \implies 7n + 9 = 2
\]

2. **Isolate the term with the variable.**
Subtract 9 from both sides:
\[
7n + 9 - 9 = 2 - 9 \implies 7n = -7
\]

3. **Solve for \( n \).**
Divide both sides by 7:
\[
n = \frac{-7}{7} \implies n = -1
\]

So the steps in order are:
1. Combine like terms.
2. Isolate the term with the variable.
3. Solve for \( n \).

The final solution is \( n = -1 \).
