Answer 1

To solve the equation $3n+9+4n=2$, we can follow these steps:

Step 1:

Combine like terms on the left side. $$3n+4n+9=2$$ This simplifies to: $$7n+9=2$$

Step 2:

Subtract 9 from both sides to isolate the term with $n$. $$7n+9-9=2-9$$ This gives us: $$7n=-7$$

Step 3:

Divide both sides by 7 to solve for $n$. $$n=\frac{-7}{7}$$ This simplifies to: $$n=-1$$

So the complete ordered steps to solve the equation are:

1. Combine like terms: $7n+9=2$
2. Subtract 9 from both sides: $7n=-7$
3. Divide by 7: $n=-1$
