47 + (5 + 5 * 3) – 7 What is the first step you should take when solving this number sentence?

Homework hint You must add or subtract first. Use the Rules of Equality. 8V + 7 = 23 2X + 9 = 25 These are called two-step equations.

Solving equations Find the variable Figure out what you are doing to the variable (adding to it, subtracting from it, multiplying it, or dividing it) Remember: how much are you adding or subtracting, multiplying or dividing by what? Do EXACTLY the opposite using one of the Rules of Equality (Addition, subtraction, multiplication, or division)

Solving Equations Find the variable Figure out what you are doing to the variable (adding to it, subtracting from it, multiplying it, or dividing it) Move the constant to the other side of the equation by doing the opposite.
