Solve the equation 2x + 5 = 17.
Answer and explanation
Correct answer: A. x = 6, after subtracting 5 and dividing 12 by 2
- Step 1: Subtract 5 from both sides: 2x = 12. Step 2. Divide by 2: x = 6. Answer: x = 6. Why not the others: the other values come from adding instead of subtracting or from dividing before isolating the term in x.
