Solve the equation 5x + 12 = 82.
Answer and explanation
Correct answer: D. 14
- Step 1: Subtract 12: 5x = 70. Step 2. Divide by 5: x = 14. Answer: 14. Why not the others: 19: the constant was added instead of subtracted. 16: the constant term was ignored. 65: the terms were subtracted without dividing.
