To solve for \( x \) in the equation \(-4x + 1 = 21\), follow these steps: 1. Subtract \( 1 \) from both sides: \[ -4x + 1 - 1 = 21 - 1 \] This simplifies to: \[ -4x = 20 \] 2. Next, divide both sides by \(-4\): \[ x = \frac{20}{-4} \] This simplifies to: \[ x = -5 \] So the solution is: \[ x = -5 \]
