1. **State the problem:** Solve the equation $(x-18)-8=-28$ for $x$. 2. **Write down the equation:** $$ (x-18)-8 = -28 $$ 3. **Simplify the left side:** $$ x - 18 - 8 = -28 $$ $$ x - 26 = -28 $$ 4. **Isolate $x$ by adding 26 to both sides:** $$ x - 26 + 26 = -28 + 26 $$ $$ x = -2 $$ 5. **Final answer:** $$ x = -2 $$ This means the value of $x$ that satisfies the equation is $-2$.
