Example Questions
Example Question #1 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
Solve for :
Isolate the variable to one side.
Subtract from both sides:
Example Question #2 : One Step Equations
Solve for :
We need to isolate by dividing by 3.
Remember, what you do on one side, you must do on the other side.
Since you divided by , you also have to divde by :
Example Question #3 : One Step Equations
Solve for :
To solve this you must isolate your by subtracting 1 from both sides to get
or
Example Question #4 : One Step Equations
Solve for x:
Step 1: isolate x
Step 2: solve
If it's helpful, when you subtract a positive integer from a negative integer, you can think of it in terms of absolute value:
Example Question #5 : One Step Equations
Solve for :
6
4
7
8
9
8
To solve this equation, isolate by dividing both sides of the equation by 8:
Example Question #2 : Evaluate Expressions: Ccss.Math.Content.6.Ee.A.2c
To solve this equation, isolate the variable. Since 3x is a multiplication operation, do the opposite (division) to remove the 3. Keep in mind that you must do the same step on each side of the equation every time you change something.
Example Question #4 : One Step Equations With Integers
To solve this equation, you must isolate the variable. In order to do this, do the opposite operation (division) to move the 9 to the other side of the equation. Keep in mind you must do the same step on each side of the equation every time you change something.
Your result shoud look like this:
Example Question #5 : One Step Equations With Integers
Isolate the variable by dividng both sides by 2:
Your answer should be the following:
Example Question #6 : One Step Equations With Integers
To solve this equation, isolate the variable. To do this, move the 2 to the other side of the equation. Do this by doing the opposite operation (division). Keep in mind you must do the same step on each side of the equation every time you change something.
Your answer should look like this:
Example Question #7 : One Step Equations With Integers
Solve for :
Divide both sides of the equation by 6:
Your result should be:
