To solve the equation −3x + 4 = −8, follow these steps:
Step 1: Isolate the variable term. Subtract 4 from both sides of the equation: \[ -3x + 4 - 4 = -8 - 4 \] This simplifies to: \[ -3x = -12 \]
Step 2: Solve for x by dividing both sides by -3: \[ x = \frac{-12}{-3} \] This simplifies to: \[ x = 4 \]
Solution: \( x = 4 \)
