+# Grandma gave Bryce and Carter some raisins. Bryce received 6 more raisins than Carter, and Carter received half the number of raisins Bryce received. How many raisins did Bryce receive?
+# Step 1: Let $b$ be the number of raisins Bryce received and $c$ be the number of raisins Carter received.
+# Step 2: We are given that $b = c + 6$ and $c = \frac{1}{2}b$.
+# Step 3: Substituting the second equation into the first equation, we get $b = c + 6 = \frac{1}{2}b + 6$.
+# Step 4: Simplifying, we have $b = \frac{1}{2}b + 6$.
+# Step 5: Subtracting $\frac{1}{2}b$ from both sides, we get $\frac{1}{2}b - b = 6$.
+# Step 6: Simplifying further, we have $\frac{1}{2}b - 2b = 6$.
+# Step 7: Combining like terms, we have $-\frac{1}{2}b = 6$.
+# Step 8: Multiplying both sides by $-2$, we get $b = -12$.
+# Step 9: Therefore, Bryce received $\boxed{-12}$ raisins.The answer is: -12
