1. **State the problem:** Solve the equation $-3 = -4 + c$ for $c$. 2. **Isolate the variable:** To solve for $c$, add 4 to both sides of the equation to cancel out the $-4$ on the right side. 3. **Show intermediate step with cancellation:** $$-3 + \cancel{4} = \cancel{-4} + c + 4$$ 4. **Simplify both sides:** $$-3 + 4 = c$$ $$1 = c$$ 5. **Final answer:** $$c = 1$$ This means the value of $c$ that satisfies the equation is 1.
