1. **State the problem:** Simplify the expression $$6r + 7 + 2r + 46r + 7 + 2r + 4$$. 2. **Combine like terms:** Group the terms with $r$ and the constant terms separately. $$6r + 2r + 46r + 2r + 7 + 7 + 4$$ 3. **Add the coefficients of $r$:** $$6r + 2r + 46r + 2r = (6 + 2 + 46 + 2)r = 56r$$ 4. **Add the constant terms:** $$7 + 7 + 4 = 18$$ 5. **Write the simplified expression:** $$56r + 18$$ **Final answer:** $$56r + 18$$
