Solve for \( b \) \[ \frac{1}{4}(b+c-d)=a \]

To isolate \( b \) in the equation \( \frac{1}{4}(b+c-d)=a \), we first eliminate the fraction by multiplying both sides by 4: \[ b + c - d = 4a \] Next, we need to solve for \( b \) by rearranging the equation: \[ b = 4a - c + d \] So, the solution for \( b \) is: \[ b = 4a + d - c \] Feel free to let me know if you have more math-related questions!
