Example Questions

Example Question #2 : Reasoning With Equations & Inequalities

Solve for .

Possible Answers:

Correct answer:

Explanation:

To solve for , first combine like terms.

On the left-hand side of the equation there are two terms that contain . Therefore, add  and  together.

Now, move the  term from the left-hand side to the right-hand side. To accomplish this, subtract  from both sides.

   

                     

_____________________

               

Next, to isolate , subtract the constant from the right-hand side of the equation to the left-hand side.

Example Question #2 : Reasoning With Equations & Inequalities

Solve for .

Possible Answers:

Correct answer:

Explanation:

To solve for , first combine the like terms on the left-hand side of the equation.

Therefore, the equation becomes,

Now, move all the variables to the right-hand side of the equation by adding  to both sides.

         

____________________

From here, subtract the constant on the right-hand side from both sides of the equation.

    

              

_______________

 

Lastly, divide by three on both sides of the equation to solve for .

Example Question #2 : Reasoning With Equations & Inequalities

Solve for .

Possible Answers:

Correct answer:

Explanation:

To solve for , first subtract one from both sides to combine the constant terms.

        

____________

From here, multiply by two on both sides to solve for .

The two in the numerator cancels the two in the denominator on the left-hand side of the equation; thus, isolating .

Example Question #3 : Solving An Equation Step By Step: Ccss.Math.Content.Hsa Rei.A.1

Solve for .

Possible Answers:

Correct answer:

Explanation:

To solve for  first combine the constant terms by adding two to both sides of the equation.

       

_____________

From here, multiply each side of the equation by 3 to solve for .

The three in the numerator cancels out the three in the denominator on the left-hand side of the equation; thus, solving for .

Example Question #7 : Solving An Equation Step By Step: Ccss.Math.Content.Hsa Rei.A.1

Solve for .

Possible Answers:

Correct answer:

Explanation:

First, combine like terms on both sides of the equation.

On the left-hand side:

Thus the equation becomes,

Now, subtract  from both sides.

Lastly, divide by negative one on both sides.

Example Question #8 : Solving An Equation Step By Step: Ccss.Math.Content.Hsa Rei.A.1

Solve for .

Possible Answers:

Correct answer:

Explanation:

First, subtract  from both sides to get the variables on one side.

  

              

____________________

From here, add ten to both sides to get all constants on one side, and solve for .

      

_______________

Example Question #11 : Solving An Equation Step By Step: Ccss.Math.Content.Hsa Rei.A.1

Solve for .

Possible Answers:

Correct answer:

Explanation:

First, combine like terms on the left-hand side of the equation.

Now, the equation is

From here, subtract  from both sides.

  

           

___________________

Next, subtract five to both sides.

          

_____________

Finally, divide both sides of the equation by two.

Example Question #12 : Reasoning With Equations & Inequalities

Solve for .

Possible Answers:

Correct answer:

Explanation:

To solve for , first combine like terms by adding  to both sides.

Next, add  to both sides.

From here, divide by  to solve for .

Example Question #11 : Reasoning With Equations & Inequalities

Solve for .

Possible Answers:

Correct answer:

Explanation:

To solve for , square both terms to cancel out the square root sign on the left-hand side.

Next, add two to both sides of the equation.

      

_____________

From here, check for extraneous solutions by substituting the value found for  into the original equation.

Since the square root of one is either positive or negative one, the solution found is verified.
