Question

solve $n + 7.1 = 8.6$. write your answer as a decimal to the nearest tenth.
$n = \underline{\quad\quad}$

Explanation:

Step1: Subtract 7.1 from both sides

To solve for \( n \) in the equation \( n + 7.1 = 8.6 \), we subtract 7.1 from both sides of the equation. This is based on the subtraction property of equality, which states that if we subtract the same number from both sides of an equation, the equation remains balanced.
\[
n + 7.1 - 7.1 = 8.6 - 7.1
\]

Step2: Simplify both sides

Simplifying the left - hand side, \( n+7.1 - 7.1=n \). Simplifying the right - hand side, we calculate \( 8.6−7.1 = 1.5 \).

Answer:

\( 1.5 \)
