Example Question #2661 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Solve the following equation: 

Possible Answers:

Correct answer:

Explanation:

To solve the equation, you must get  by itself on one side of the equation.  

The first step would be to eliminate the constant  which can be done by subtracting it from both sides.

 This would result in 

 

.  

Then we must get rid of the  so you must undue the multiplication by division on both sides.

  

so the final answer is .

Example Question #2661 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Find g, if  a,b, and c are all equal to 2

Possible Answers:

Correct answer:

Explanation:

Find g, if  a,b, and c are all equal to 2

To solve this equation, first plug in 2 for each variable:

Next, simplify the equation:

So, we get:

Next, take the reciprocal of both sides to get our answer:

Example Question #543 : Algebraic Concepts

Solve the following equations when .

Possible Answers:

Correct answer:

Explanation:

The first step to solve this equation is to plug in your know variable  with the value given, .  

Now you have an expression that reads  and we now solve for .  

First you must move the constant  by adding  to both sides resulting in, 

.  

The last step is to divide both sides by  resulting in,

.

Example Question #544 : Algebraic Concepts

Solve for  when 

Possible Answers:

Correct answer:

Explanation:

The first is to plug in the  value given in the problem leaving us with,

 .  

The next step is to complete the division which is 

.  

Then you add the constant and that gives you an answer of,

 .

Example Question #545 : Algebraic Concepts

Solve for :

Possible Answers:

Correct answer:

Explanation:

This is a two-step equation.  The first step is to isolate the variable.  Subtract 2.3 from both sides of the equation:

Divide both sides of the equation by the coefficient which is 9:

Example Question #546 : Algebraic Concepts

Possible Answers:

Correct answer:

Explanation:

To isolate the variable, subtract 3 from both sides of the equation:

Multiply both sides of the equation by the reciprocal of  which is 

 

Example Question #341 : How To Find The Solution To An Equation

Find the solution to the following equation when .

Possible Answers:

Correct answer:

Explanation:

Find the solution to the following equation when .

To solve this equation, we should plug in 6 wherever there is a t, and simplify.

So, our answer when t=6 is 0.

Example Question #552 : Algebraic Concepts
