Question

1. 67.9 = c - 4.45

Explanation:

Step1: Add 4.45 to both sides

To solve for \( c \), we add 4.45 to both sides of the equation \( 67.9 = c - 4.45 \). This gives us \( 67.9 + 4.45 = c - 4.45 + 4.45 \).

Step2: Simplify both sides

Simplifying the left side: \( 67.9 + 4.45 = 72.35 \). Simplifying the right side: \( c - 4.45 + 4.45 = c \). So we get \( c = 72.35 \).

Answer:

\( c = 72.35 \)
