To solve for \( a \) in the equation \( 4 - 7a = 3 - a + 13 \), start by simplifying the right side. Combine like terms: \[ 3 + 13 = 16, \] so the equation becomes \[ 4 - 7a = 16 - a. \] Next, add \( 7a \) to both sides to isolate the variable: \[ 4 = 16 + 6a. \] Now, subtract 16 from both sides: \[ 4 - 16 = 6a, \] which simplifies to \[ -12 = 6a. \] Dividing both sides by 6 gives: \[ a = -2. \] So, \( a = -2 \) is your solution! Happy calculating!
