What would we do to both sides to solve this equation for n?

Question

n + 1.2 = 6.4

Answer 1

To solve the equation $n+1.2=6.4$ for $n$, you can isolate $n$ by subtracting $1.2$ from both sides of the equation. Here are the steps:

1. Start with the original equation: $$n+1.2=6.4$$

2. Subtract $1.2$ from both sides: $$n+1.2-1.2=6.4-1.2$$

3. Simplify both sides: $$n=6.4-1.2$$

4. Calculate $6.4-1.2$: $$6.4-1.2=5.2$$

So, the solution for $n$ is: $$n=5.2$$
