Question

One method for solving 3(x-4)=18 is to divide by3, then add4. Which method would also result in the correct answer?

Answer 1

Another method for solving 3(x-4)=18 is to expand the equation first, then simplify. After expanding the equation, we would have 3x - 12 = 18. From here, we can add 12 to both sides of the equation to isolate the variable, resulting in 3x = 30. Finally, dividing both sides by 3 would give us the correct answer, x = 10.
