It takes two steps to solve an equation or inequality that has more than one operation:
- Simplify using the inverse of addition or subtraction.
- Simplify further by using the inverse of multiplication or division.
Also asked, what is a 2 step equation example?
An equation that needs two steps to solve. Example: 5x − 6 = 9. Step 1: Add 6 to both sides: 5x = 15. Step 2: Divide both sides by 5: x = 3. Linear Equations often need two steps to solve.
Also, what is the golden rule of solving an equation? Recap: The Golden Rule That which you do to one side of an equation, you must also do to the other. Remember that rule? I hope so because, as we learned about last time, this golden rule of equation solving is going to be super important in all of your future equation solving endeavors.
Moreover, what are the 4 steps to solving an equation?
A 4-Step Guide to Solving Equations (Part 2)
- Step 1: Simplify Each Side of the Equation. As we learned last time, the first step in solving an equation is to make the equation as simple as possible.
- Step 2: Move Variable to One Side.
What is a two step math problem?
In a math word problem, the information needed to solve the problem is provided in words rather than numbers or symbols. While many of these problems have only one step, a two-step word problem requires you to solve two different equations before coming to the answer.

What’s a one step equation?
A one-step equation is an algebraic equation you can solve in only one step. Once you’ve solved it, you’ve found the value of the variable that makes the equation true. To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself.
What is an example of a one step equation?
