Solve for x: 5x + 5 = 65.
Answer and explanation
Correct answer: C. 12
- Step 1: Subtract 5 from both sides: 5x = 60. Step 2. Divide both sides by 5: x = 12. Answer: 12. Why not the others: 14: this adds 5 instead of subtracting it. 13: this ignores the 5. 55: this subtracts the coefficient instead of dividing by it.
