Solve for x: 3x + 4 = -8.

Ax = -4
Bx = 4
Cx = -12
Dx = 12
Answer & Solution
Correct answer: A. x = -4
1. Subtract 4 from both sides to leave the variable term alone: 3x = -8 - 4. 2. Combine: 3x = -12. 3. Divide both sides by 3: x = -4. 4. Check: 3(-4) + 4 = -12 + 4 = -8, a true statement, while x = -12 is the trap of stopping before dividing by 3. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 2 "Solving Linear Equations and Inequalities", section 2.3 Solve Equations with Variables and Constants on Both Sides_
