The best method of solving two-step equation is "Apply the multiplication property of equality first, and then apply the addition property of equality to isolate the variable"

How to solve two step equation

For instance:

40 = 5(x) - 5

40 = 5x - 5

  • Add 5 to both sides

40 + 5 = 5x

45 = 5x

x = 45/5

x = 9

Therefore, the correct answer is "Apply the multiplication property of equality first, and then apply the addition property of equality to isolate the variable".
