e.g. 5n-30=-20

30+30 which then cancels out

5n=-20

5n over 5 which cancels to just n

n=-20

-20 +30 which is 10 and 10 divided by 5 which is 2

n=2

How do you solve two-step equations with fractions?

Equations can be tricky, and solving two step equations is an important step beyond solving equations in one step. Solving two-step equations will help introduce students to solving equations in multiple steps, a skill necessary in Algebra I and II. To solve these types of equations, we use additive and multiplicative inverses to isolate and solve for the variable. Solving Two Step Equations Involving Fractions This video explains how to solve two step equations involving fractions.


How do you solve two step equations with Integers?

How do you solve two-step equations with fractions on one side?

Assuming you want to get rid of the fractions, you can multiply both sides of the equations by the greatest common factor of the fractions. Then you can solve the equation normally.


How do you do two step equations?

You will have to break it down, for example: 5x + 40= 60 -40 -40 ----------- 0 20 so 20 divided by 5 is 4 so x equals 4, thats how you do it,.


What is the different between one-step equations and two-step equations?

okay one step equations are when you do 1 problem and two step is when you do the same procedure twice


How can you use a graph to solve systems of equations?

You can use a graph to solve systems of equations by plotting the two equations to see where they intersect


How do you solve a system of equations by graphing?

Write each equations in popular form. ... Make the coefficients of one variable opposites. ... Add the equations ensuing from Step two to remove one variable. Solve for the last variable. Substitute the answer from Step four into one of the unique equations.


How does factoring help solve quadratic equations?

Well, that's one method to solve the quadratic equation. Here is an example (using the symbol "^" for power): solve x^2 - 5x + 6 = 0 Step 1: Convert the equation to a form in which the right side is equal to zero. (Already done in this example.) Step 2: Factor the left side. In this case, (x - 3) (x - 2) = 0 Step 3: Use the fact that if a product is zero, at least one of its factors must be zero. This lets you convert the equation to two equations; x - 3 = 0 OR x - 2 = 0 Step 4: Solve each of the two equations.


How do you solve linear equations by using elimination?

You multiply one or both equations by some constant (especially chosen for the next step), and add the two resulting equations together. Here is an example: (1) 5x + 2y = 7 (2) 2x + y = 3 Multiply equation (2) by -2; this factor was chosen to eliminate "y" from the resulting equations: (1) 5x + 2y = 7 (2) -2x -2y = -6 Add the two equations together: 3x = 1 Solve this for "x", then replace the result in any of the two original equations to solve for "y".

Steps of how to solve a system of equations by substitution?

Step one is by expressing one of the equation into one term that is taking one unknown in the form of other. Step two is replacing the unknown into equation 2. Step 3 is replacing the found unknown into one of initial equations to find the other unknown.


How is solving a two step equation different from one step equations?

In a two step equation, you need to do another step.
