Question 6 on the MAT0020/24C Beginning Algebra State Exam

Solve a Linear Equation

 

6.  Solve for r:                                                            

 

A.                      B.                    C.                      D. 

 

Solution:

 

Solve for r: 

 

The first step would be to simplify both sides of the equation using distributive property.

 

 

The next step would be to move the variables to the same side of the equation.

 

 

The next step is to move the variables to other side of the equation.

 

 

The next step is to solve for r and simplify solution.

 

 

The solution is: 

 

Note:  You can check your solution by substituting it back into your equation.
