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

n + 1.2 = 6.4

1 answer

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: \[ n = 5.2 \]
