Solve the equation 8x + 19 = 107.
Answer and explanation
Correct answer: D. 11
- Step 1: Subtract 19: 8x = 88. Step 2. Divide by 8: x = 11. Answer: 11. Why not the others: 16: the constant was added instead of subtracted. 13: the constant term was ignored. 80: the terms were subtracted without dividing.
