Question

1. -12 = 4 + c

Explanation:

Step1: Subtract 4 from both sides

To solve for \( c \), we need to isolate it. Subtract 4 from both sides of the equation \(-12 = 4 + c\). So we have \(-12 - 4 = 4 + c - 4\).

Step2: Simplify both sides

Simplifying the left side: \(-12 - 4 = -16\). Simplifying the right side: \(4 + c - 4 = c\). So we get \(c = -16\).

Answer:

\( c = -16 \)
