Question

1. \\( b + 4.25 = 11.4 \\)

Explanation:

Step1: Subtract 4.25 from both sides

To solve for \( b \), we need to isolate it. We do this by subtracting 4.25 from both sides of the equation \( b + 4.25 = 11.4 \).
\[
b + 4.25 - 4.25 = 11.4 - 4.25
\]

Step2: Calculate the result

Simplify both sides. On the left side, \( 4.25 - 4.25 = 0 \), so we are left with \( b \). On the right side, we calculate \( 11.4 - 4.25 \).
\[
b = 11.4 - 4.25 = 7.15
\]

Answer:

\( b = 7.15 \)
