What is two step equations used for?
A two-step equation is an algebraic equation that takes you two steps to solve. You’ve solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.
What’s an example of a two step equation?
Equations that can be solved in exactly two steps and gives the final value of the variable in two steps are called two step equations and are algebraic equations. Generally, two step equations are of the form ax + b = c, where a, b, c are real numbers. A few examples of two step equations are: 2x + 3 = 7.

What happens to the order of operations when you’re solving a two step equations?
When solving a two-step equation, you will always need to undo the addition and subtraction first. If you follow the order of operations, you need to multiply and divide before you add or subtract.
When solving two step equations do the order of operations apply?
Solving a two-step equation involves working backward concerning the order of operations (PEMDAS). In this case, multiplication and division are preceded by addition and subtraction. Tips for Solving Two-step equations include: Always apply addition or subtraction to remove a constant.
What are some real life examples of linear equations?
Real life examples include:
- Calculating wages based on an hourly pay rate.
- Calculating medicine doses based on patients’ weights.
- Calculating the perimeters of squares.
- Hiring a car if a deposit is paid and there is an hourly charge.
Can you give other real life situations where a linear equation in two variables is applied?
You can apply linear equations to various real life situations, such as recipe ingredients, weather predications and financial budgets.
In what way can you apply solving mathematical problems in real life situations?
When am I ever going to use math?
- Math Helps You Build Things. Ask any contractor or construction worker–they’ll tell you just how important math is when it comes to building anything.
- Math is in the Grocery Store.
- Math Makes Baking Fun.
- Math Takes the Risk Out of Travel.

How do you solve two step equations step by step?
1) First, add or subtract both sides of the linear equation by the same number. 2) Secondly, multiply or divide both sides of the linear equation by the same number. 3)* Instead of step #2, always multiply both sides of the equation by the reciprocal of the coefficient of the variable.

How can equation and inequalities be used in real life situations?
Actually, Originally Answered: How can equation and inequalities be used real life situations? One example is the Squeeze theorem where we can squeeze a complicated function between two simpler functions & use results on the simpler functions to prove bounds on the more complicated function.
How did you use equations in your daily life?
You basically used equations everyday without even notice. Like when you have to calculate “How many dollars does the sum of your grocery stuffs equal to?”. Or a more complicated situation, if you need to be in the meeting at 9:30am, the travel distance is 10km and you can only leave after 8:30am, your driving speed should equal “x” km/h.”
How do you solve a linear equation with an unknown variable?
As the name of this linear equation suggests, it requires two steps in order to solve for the unknown variable. Generally, the first step involves getting rid of the number “farthest” from the term with a variable being solved. Then, we eliminate the number “closest” to the variable.
